Synchronization code methods

Abstract

A system, method and computer software product are provided. One embodiment of the present invention provides a method for generating and employing numerical sequences that may be used for synchronization codes. In one embodiment of the present invention, the derivation of numerical sequences, or codes is based on an encoding algorithm. These codes enable synchronization between communicating devices, and may also be used for channelization. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

1 . An ultra-wideband communication system, comprising: 
 at least two groups of ultra-wideband communication devices; and    a set of synchronization codes assigned to each group of communication devices;    wherein each assigned set of synchronization codes allows each group of communication devices to communicate with other communication devices in the same group, without interfering with the other groups of communication devices.    
     
     
         2 . The communication system of  claim 1 , wherein each assigned set of synchronization codes is transmitted using a pseudo-random hopping sequence.  
     
     
         3 . The communication system of  claim 1 , wherein each communication device is assigned a specific synchronization code from the assigned set of synchronization codes.  
     
     
         4 . The communication system of  claim 1 , wherein each synchronization code is included within a frame that comprises a data payload section and an error detection section.  
     
     
         5 . The communication system of  claim 1 , wherein each synchronization code is transmitted using a substantially continuous sinusoidal waveform.  
     
     
         6 . The communication system of  claim 5 , wherein the substantially continuous sinusoidal waveform has a duration that ranges between about 1 microsecond to about 1 millisecond.  
     
     
         7 . The communication system of  claim 5 , wherein the substantially continuous sinusoidal waveform has less than a 20% fractional bandwidth.  
     
     
         8 . The communication system of  claim 1 , wherein each synchronization code is transmitted using an ultra-wideband signal.  
     
     
         9 . The communication system of  claim 8 , wherein the ultra-wideband signal has a duration that ranges between about 10 picoseconds to about 1 microsecond.  
     
     
         10 . The communication system of  claim 8 , wherein the ultra-wideband signal has a power that can range between about +30 dBm to about −60 dBm, as measured at a single frequency.  
     
     
         11 . The communication system of  claim 8 , wherein the ultra-wideband signal has greater than a 20% fractional bandwidth.
