Abstract :
This paper presents the Bit Error Rate characteristics of Ultra Wide Band signals made by using the low pulse duty factor and spreading code in the body surface channel, body to external channel as well as multiuser multipath channel. Additionally, this paper presents the distance-mean transmitting power performances, yielded from the BER characteristics results in the body surface channel and body to external channel. From the results, it was found that the spreading code increases the time resolution of separating paths in using RAKE receiver and decreases the multiuser interference in multipath channel.
