Software RF (Radio Frequency) defined systems have improved the speed and flexibility of testing and measuring RF standards. Such systems make it possible for researchers to implement, test and perform analysis to emerging technologies. In this work, the implementation of a digital communication system is used to test the effects of bias coding on the performance of a multilevel digital communication system in terms of BER (Bit Error Rate) and power consumption which has received little attention from researchers but is nonetheless well worthy of research. Signal Bias changes the statistics...
