Performance Analysis of Hard Decision and Soft Decision Algorithms Over In Vivo Radio Channel

Abstract

AbstractBER performance of soft and hard decisions over in-vivo radio channel using ultra-wideband (UWB) frequencies (3.10–10.60 GHz) is presented in this paper. BER performance is calculated by comparing the message decoded by soft and hard decision algorithms with the transmitted message. This article compares the BER performance of soft and hard decisions over in vivo radio channels with Eb/No = (0–14 dB). We used MATLAB for this experiment. BER performance is better with a soft decision decoding algorithm in the log domain than with a hard decision algorithm, regardless of the Eb/No Levels.
