Presented in this paper are low-power, reconfigurable adaptive CDMA multiuser receiver architectures developed via dynamic algorithmic transforms (DAT). The architectures achieve low-power operation via run-time reconfiguration of receiver complexity to match the requirements of a time-varying multiuser channel. Simulation results with 0.25 μm, 2.3 V CMOS technology parameters indicate that the proposed architectures have high resistance to the near-far problem, and can achieve up to 60.4% in power savings compared to architectures without DAT depending on the interference situation.
