In this paper, the complexity and the performance of the list parallel interference cancellation (PIC) detection algorithm is compared to the ones of the K-best list sphere detector (LSD) and the increasing radius (IR)-LSD in a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system. The detectors are used as a soft MIMO detector to approximate the a posteriori probability (APP) algorithm in an iterative receiver to jointly decode the transmitted bits and to estimate the channel state. According to the results, the list PIC algorithm with a proper initialization gives some performance gain over the K-best LSD and loses only slightly to the IR-LSD. The IR-LSD is found to be the least complex of the algorithms when the number of visited nodes is measured. © 2008 IEEE.
