Abstract :
The root mean square (RMS) delay spread and coherence bandwidth are examined based on measurement for a wide band human body channel. Using the results, the relation between these two wideband channel parameters is evaluated. The inter-symbol interference (ISI) effect on the performance of the frequency selective digital transmission (FSDT) is investigated by modeling the time dispersive human body channel as a finite impulse response (FIR) filter. Then, the compatible required transmitter power is computed for a reliable FSDT communication link.
