Contents 1. Introduction
Demand has recently been increasing for wireless personal area network (WPAN) communication with integrated multimedia traffic that requires high bit rate transmission [1]–[4]. In this effort, both the Bluetooth SIG and IEEE 802.15 committee are working for the high-rate version that are commensurate with the distribution of high-quality video and high fidelity audio for WPAN applications, as depicted in Fig. 1, along with a reduction in interference with various wireless communication systems, such as IEEE 802.11b, HomeRF, and Bluetooth [1] [2].
