Method and Apparatus for Band Separation for Multiband Communication Systems

摘要

Aspects of a method and apparatus for band separation for multiband communication systems are provided. One or more circuits for use in a transceiver may comprise a triplexer and a leakage processing module. The triplexer may comprise a first port, a Multimedia Over Coaxial Alliance (MoCA) port, a television upstream port, and a television downstream port. The leakage processing module may comprise a television downstream input port, a cable television downstream output port, a MoCA port, and a cable television upstream port. The leakage processing module may be operable to (1) process a MoCA signal to generate a first compensation signal; (2) process a cable upstream signal to generate a second compensation signal; (3) process a filtered signal based at least in part on the first and second compensation signals; and (4) output the processed filtered signal via the cable television downstream output port of said leakage processing module.

1. A system comprising:
one or more circuits for use in in a transceiver, wherein:
said one or more circuits comprise a filter and a leakage processing module;said filter comprises a first port, a first-protocol port, a second-protocol upstream port, and a second-protocol downstream port;said leakage processing module comprises a second-protocol downstream input port, a second-protocol downstream output port, a first-protocol port, and a second-protocol upstream port; andsaid leakage processing module is operable to:
process a first-protocol signal received via said first-protocol port of said leakage processing module via a first impedance network to generate a first compensation signal;process a second-protocol signal received via said second-protocol upstream port of said leakage processing module via a second impedance network to generate a second compensation signal;receive a filtered signal received from said second-protocol downstream port of said filter;subtract said first compensation signal from said signal received from said second-protocol downstream portsubtract said second compensation signal from said signal received from said second-protocol downstream port to generate a processed filtered signal; andoutput said processed filtered signal via said second-protocol downstream output port of said leakage processing module.
