Abstract(in English) | In order to increase the link capacity, this paper investigates the effectiveness of interference rejection weight control (IRWC) for pilot symbol-assisted coherent multistage interference canceller (PSA-COMSIC) that uses recursive channel estimation (RCE). First, bit error rate expression of the serial (successive) and parallel type hard decision multistage interference canceller (MSIC) with IRWC using Gaussian approximation for multiple access interference (NRI) is presented in a simple model. It is theoretically shown that IRWC is effective for mitigating the interference replica generation error in hard decision MSIC. The simulation results demonstrate that, interference-limited channels where the back ground noise is negligible, the capacity of serial type PSA-COMSIC using IRWC is about 10% higher than that without IRWC. |
