The improvement in propagation characteristics of WBAN is required to develop the high quality WBAN system. In this paper, the error rate performance of channel model CM4 of WBAN is evaluated for different modulation schemes for distinct body directions for UWB. The effect of rake receiver structure is also assessed. The bit error rate has been obtained by using BPSK (Binary Phase Shift Keying), M-ary PAM (Pulse Amplitude Modulation) and M-ary BOK (Bi- orthogonal Keying). The evaluation is done by calculating the value of Signal to noise ratio for targeted Bit Error Rate for different body directions using different modulation scheme. The obtained results give an assessment to better understand the effect of modulation schemes selection on error rate performance of the WBAN channel.
