QUANTIZATION-BASED MODULATION AND CODING SCHEME FOR MOBILE FRONTHAUL

摘要

A method implemented in a communication device, including receiving, by the communication device, quantized in-phase and quadrature (IQ) bits of an input signal, separating, by the communication device, the IQ bits into most-significant-bits (MSBs) and least-significant-bits (LSBs), encoding, by the communication device, the MSBs to generate encoded MSBs, modulating, by the communication device, the encoded MSBs with a first modulation to generate modulated encoded MSBs, modulating, by the communication device, the LSBs with a second modulation to generate modulated LSBs, combining, by the communication device, the modulated encoded MSBs and the modulated LSBs into a combined modulated signal, and transmitting, by the communication device, the combined modulated signal to a receiver through a transmission channel.
