RBF Equalization UsingTurbo Codes In this chapter, the wideband AQAM scheme explored in the previous chapter is extended to incorporate the benefits of channel coding. Channel coding, with its error correction and detection capability, is capable of improving the BER and throughput performance of the wideband AQAM scheme. Since the wideband AQAM scheme always attempts to invoke the appropriate modulation mode in order to combat the wideband channel effects, probabilthe ity of encountering a rece
