Channel Monitoring for Improved Parameter Selection in a Communication System

Abstract

A method is provided for automatically improving throughput of an active channel in a communication system comprising: receiving input from one or more modules that identify and characterize impairments in the active channel; monitoring the input to track changes in the impairments; and changing channel parameters to improve throughput on the channel based on the changes in the impairments. Other systems and methods are disclosed.

       20 . A method for automatically improving throughput of an active channel in a communication system comprising: 
 receiving input from one or more modules that identify and characterize impairments in the active channel;    monitoring the input to track changes in the impairments; and    changing channel parameters to improve throughput on the channel based on the changes in the impairments.    
   
   
       21 . The method of  claim 20  further comprising receiving the input from different time periods and identifying impairment patterns.  
   
   
       22 . A method to automatically estimate channel throughput if a different order constellation from current constellation size is used in a communication system comprising: 
 receiving input from one or more modules that identify and characterize impairments in the channel;    analyzing the impairments to generate statistics on occurrences of impairments without using an interleaver or deinterleaver and without actually changing a used burst profile;    choosing a new constellation size; and    estimating channel throughput for the new constellation size based on the statistics on occurrences of impairments.    
   
   
       23 . The method of  claim 22  further comprising the steps of choosing forward error correction parameters different from current forward error correction parameters prior to the step of estimating channel throughput.  
   
   
       24 . The method of  claim 22  wherein the new constellation size is higher than the current constellation size.  
   
   
       25 . The method of  claim 22  wherein the new constellation size is lower than the current constellation size.  
   
   
       26 . The method of  claim 22  wherein transmission is occurring on the channel at the current constellation.  
   
   
       27 . The method of  claim 22  wherein the impairments are burst and impulse noise.  
   
   
       28 . The method of  claim 22  wherein transmission of a preamble is occurring on the channel.  
   
   
       29 . The method of  claim 22  wherein the statistics on occurrences of impairments comprises number of impairments and sequence of impairments.
