Nondata-aided joint channel estimation and equalization for OFDM systems in very rapidly varying mobile channels Authors:
Publisher and Date:(IEEE-INST Electrical Electronics Engineers Inc, 2012)This paper is concerned with the challenging and timely problem of joint channel estimation and equalization for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very rapidly time varying channels. The resulting algorithm is based on the space alternating generalized expectation maximization-maximum a posteriori probability (SAGE-MAP) technique which is particularly well suited to multicarrier signal formats. The algorithm is implemented in the ...
