Time and Frequency Domain Channel Estimation in MIMO-OFDM Co-operative Communication

Jancy Wilson, Aravind S.

MIMO-OFDM is a promising technique to achieve reliable communication in wireless communication systems. MIMO-OFDM system is incorporated with co-operative communication which increases the transmission range. Multiple input multiple output systems (MIMO) divides the input data into different data blocks and is allowed to transmit through multiple antennas. Orthogonal frequency division multiplexing (OFDM) has the ability to cope up severe channel conditions. Multiple transmit and receive antennas in OFDM systems can improve communication quality and capacity. This paper develops a low complexity channel estimation in MIMO-OFDM communication. The priori-information aided iterative hard threshold algorithm (PAIHT) is the channel estimation technique which uses prior information for obtaining accurate channel estimate of the wireless channel. Simulation results demonstrate that, the proposed scheme performs well without sacrificing spectral efficiency.
