Method and system for improving dynamic range for communication systems using upstream analog information

A computer-readable medium having stored thereon, a computer program having at least one code section for processing received signals in a communication system, the at least one code section being executable by a computer for causing the computer to perform steps comprising:

• receiving an RF signal;
• generating a plurality of narrowband signals from said received RF signals;
• converting said at least a portion of said generated plurality of upstream narrowband signals to corresponding digital signals;
• calculating an intermediate gain, which enables carrier sense detection, for each of said at least a portion of said generated plurality of upstream narrowband signals based on a power of each of said corresponding digital signals and based on whether said of each of said corresponding digital signals is clipped;
• and
• adjusting a final gain of said received RF signal based on said calculated intermediate gain of each of said at least a portion of said generated plurality of upstream narrowband signals.

A system for processing received signals in a communication system, the system comprising:

• at least one processor that enables receiving of an RF signal;
• said at least one processor enables generation of a plurality of narrowband signals from said received RF signals;
• said at least one processor enables converting of said at least a portion of said generated plurality of upstream narrowband signals to corresponding digital signals;
• said at least one processor enables calculation of an intermediate gain, which enables carrier sense detection, for each of said at least a portion of said generated plurality of upstream narrowband signals based on a power of each of said corresponding digital signals and based on whether said of each of said corresponding digital signals is clipped;
• and
• said at least one processor enables adjusting of a final gain of said received RF signal based on said calculated intermediate gain of each of said at least a portion of said generated plurality of upstream narrowband signals.
