ABSTRACT
We propose a new multiple access control (MAC) protocol based on complementary code-code division multiple access (CC-CDMA) technology to resolve collisions among access-request packets in an ultra-wideband wireless personal area network (UWB WPAN) system. We design a new access-request packet to gain higher bandwidth utilization and ease the requirement on system timing. The new MAC protocol is energy efficient and fully utilizes the specific features of a UWB WPAN system, thus the issue of complexity caused by the adoption of CDMA technology is resolved. The performance is analyzed with the consideration of signal detection error. Analytical and simulation results show that the proposed CC-CDMA-based MAC protocol exhibits higher throughput and lower average packet delay than those displayed by carrier sense multiple access with collision avoidance (CSMA/CA) protocol.
