Data communication and radio system

Abstract

Provided is a method and system for a radio system including at least one base station and terminal equipment including a receiver and a transmitter. The transmitter is structured and arranged to independently adjust a symbol rate of at least two signals and combine the two signals after adjusting the symbol rate. The transmitter then transmits the combined signal along one physical path. By adjusting the signal rate before combining the two signals, the transmitter optimizes the signal qualities of each of the signals.

What is claimed is:  
     
       1. A data transmission method used in a radio system including at least one base station and terminal equipment, the terminal equipment including at least a transmitter and a receiver, the transmitter and the receiver being adapted to communicate with each other over at least one physical channel, the method comprising: 
       receiving in the a transmitter, at least two signals, each having a unique differing signal quality requirements;  
       independently adjusting a symbol rate of the at least two received signals if a signal quality requirement of one of the at least two received signals is different from a the signal quality requirement of the other of the at least two received signals by a predetermined amount, the adjusting compensating for the difference;  
       combining the at least two received signals to produce a combined signal; and  
       transmitting the combined signal along the at least one physical path configured to carry communication between the transmitter and a receiver,  
       wherein independently adjusting a symbol rate is performed prior to combining the at least two received signals.  
     
     
       2. The method of  claim 1 , wherein the transmitter employs at least one of removal coding and repetition coding. 
     
     
       3. The method of  claim 2 , wherein the removal coding and repetition coding are performed in a predetermined manner, wherein the change in the symbol rate does not interfere with transmission of the combined signal. 
     
     
       4. The method of  claim 1 , wherein the transmitter adjusts the symbol rate of each of the at least two received signals in such a way that a symbol rate of the combined signal is kept unchanged. 
     
     
       5. The method of  claim 1 , wherein the receiver indicates to the transmitter that a need exists to change the symbol rates of the at least two received signals when the quality of one or more of the at least two received signals does not meet a predetermined quality requirement at the receiver. 
     
     
       6. The method of  claim 1 , wherein the transmitter is configured to adjust, if necessary, the symbol rate of the combined signal. 
     
     
       7. The method of  claim 1 , further comprising the transmitter interleaving the at least two received signals. 
     
     
       8. The method of  claim 1 , wherein the transmitter is configured to perform at least one of convolution coding and Reed-Solomon coding of the at least two received signals. 
     
     
       9. The method of  claim 1 , wherein the signal qualities quality requirements are signal-specific. 
     
     
       10. A radio system including at least one base station and terminal equipment, the terminal equipment at least one of which including a receiver and or a transmitter, the receiver and the transmitter being configured to communicate with each other over at least one physical channel, wherein the transmitter is structured and arranged to transmit at least two received signals over one physical path, each the received signal signals having a unique differing signal quality requirements, the transmitter comprising at least: 
       a symbol rate adjuster configured to independently adjust a symbol rate of each of the at least two received signals if a signal quality requirement of one of the at least two received signals is different from a signal quality requirement of the other of the at least two received signals by a predetermined amount; and  
       a combiner configured to combine the at least two received signals to produce a combined signal for transmission along the at least one physical path;  
       wherein the symbol rate adjuster adjusts, if necessary, the symbol rate of at least one of the at least two received signals before the combiner combines the at least two received signals.  
     
     
       11. The radio system of  claim 10 , wherein the symbol rate adjuster is configured to employ at least one of removal coding and repetition coding. 
     
     
       12. The radio system of  claim 11 , wherein the at least one of the removal coding and repetition coding is known to the transmitter and the receiver. 
     
     
       13. The radio system of  claim 10 , wherein the symbol rate adjuster is configured to change the symbol rate of the at least two received signals prior to combination in such a way that the symbol rate of the combined signal is unchanged by operation of the symbol rate adjuster. 
     
     
       14. The radio system of  claim 10 , wherein the receiver is configured to measure the quality of the at least two received signals and to indicate to the transmitter that a need exists to change the symbol rates of the at least two received signals if the quality of one or more of the at least two received signals does not meet a predetermined quality requirement at the receiver. 
     
     
       15. The radio system of  claim 10 , wherein the transmitter is configured to change, if necessary, a symbol rate of the combined signal. 
     
     
       16. The radio system of  claim 10  or  15 , wherein the transmitter is configured to interleave the at least two received signals. 
     
     
       17. The radio system of  claim 10  or  15 , wherein the transmitter is configured to perform at least one of convolution coding and Reed-Solomon coding on the at least two received signals. 
     
     
       18. The radio system of  claim 10 , wherein the signal qualities quality requirements are signal specific.
