In order to meet the growing various customers' demands, several devices must be equipped in wireless personal area network (WPAN) environment. However, it causes a high cost and complexity to satisfy compatibleness within any WPAN devices. In this letter the multi-band orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband (UWB) system is considered with multiple access scheme, time/frequency domain spreading, and enlarged dual carrier modulation (E-DCM) for multirate transmission on only one electronic device in WPAN. It is shown that the proposed system can support multirate transmission based on the parameter.
