Abstract

In this paper, the Probabilistic Data Association (PDA) detection method for Multiple-Input Multiple-Output (MIMO) detection in V-BLAST systems is extended to the Soft-In-Soft-Out (SISO) iterative signal detection problem between PDA detector and channel decoder. The SISO PDA detector can considerably reduce the PDA internal iteration numbers and avoid the near singularity problem of the effective noise covariance matrix in high signal to noise ratio (SNR). Simulations under a multiple antenna Rayleigh fading scenario show that the SISO iterative PDA detector attains a better performance.
