Performance of cooperative communications in wireless UWB body networks

This paper compares the bit error rate (BER) performance of two relaying architectures with UWB Body Network channels, namely the hybrid decode-amplify-and-forward (HDAF) and the decode-and-forward (DF) protocols. It is assumed that CM3 on-body channel model is used for the communication between the source and the relay, and off-body channel model referred as CM4 for the source-destination, and the relay-destination communications. The result shows the superiority of the proposed HDAF strategy in UWB body networks regardless of adopted modulation pattern and the SNR range.
