Comprehensive design for multirate and multicarrier communications systems

Abstract

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.
