In the previous chapter, introduced the joint Adaptive Quadrature Amplitude Modulation we (AQAM) and equalization scheme, where the pseudo-SNR outputof the DFE was used at the as the modulation mode switching metric in order to mitigate the effectsa wideband fading of AQAM scheme is extended to incorporate benefits the channel. In this chapter, the wideband of channel coding. The general motivation for using channel coding is to exploit the error correction and the error detection capability the
