Signal acquisition in a multimode environment
First Claim
1. A transmitter comprising:
- a symbol mapping circuit configured to map a frame of bits to a frame of symbols, said symbols corresponding to a determined modulation scheme; and
circuitry configured to convert said frame of symbols to a physical layer signal and transmit said physical layer signal onto a communication medium,wherein;
said circuitry comprises a nonlinear distorter circuit configured to process said physical layer signal such that a first portion of said physical layer signal not including payload data is a linear signal and a second portion of said physical layer signal including payload data is a nonlinear signal.

Abstract
A transmitter comprises a symbol mapper operable to map a frame of bits to a frame of symbols, where the symbols correspond to a determined modulation scheme, and circuitry operable to convert the frame of symbols to a physical layer signal and transmit the physical layer signal onto a communication medium. The circuitry is operable to process the physical layer signal such that a first portion of the physical layer signal is a first type of signal (e.g., a linear signal and/or non-ISC signal) and a second portion of the physical layer signal is a second type of signal (e.g., nonlinear signal and/or ISC signal). The first portion of the physical layer signal may comprise a header, a preamble, and/or a payload of the frame. The second portion of the physical layer signal may comprise a header, a preamble, and/or a payload of the frame.
