Abstract :
The paper presents the impact caused by channel estimation error on the multiuser detection scheme employing adaptive parallel interference cancellation (APIC) in a Rayleigh fading time-multiplexed pilot channel. The simulation results confirm that a certain level of channel estimation accuracy is required to ensure the performance improvement of the APIC algorithm. Based on the WMSA channel estimation method and the former adaptive PIC structure, an improved algorithm (APIC II) is proposed, in which a better estimate of channel parameters is obtained and more precise data detection is carried out. Its effectiveness is verified by the simulation result
