The design of signal scaling for a 16-QAM multi-carrier transceiver realized on a DSP platform

摘要

A signal scaling design procedure, to obtain the best noise performance for a 16-QAM discrete multi-carrier transceiver, realized on a digital signal processing (DSP) platform, is presented. The experimental results demonstrate that under the proper scaling, the bit error rate (BER) of the multi-carrier transceiver can approach a very small value. The proposed signal scaling method can be applied to other DSP based multicarrier communications systems.
