TY - JOUR T1 - BEM-based SISO detection of orthogonal space-time block codes over frequency flat-fading channels. JF - IEEE Transactions on wireless communications A1 - Gallo, A.S LA - English UL - https://tuklas.up.edu.ph/Record/UP-99796217609624712 AB - The expectation-maximization algorithm for maximum a posteriori (MAP) estimation of a random vector is applied to the problem of detection of orthogonal space-time block codes over time-selective Rayleigh fading channels. This results in a soft-in soft-out detection algorithm suitable for iterative detection/decoding schemes. Simulation results show that the error performance of the proposed detection algorithm is very close to that of a MAP detector endowed with an ideal knowledge of the channel state if the fading rate is not too fast.
