Channel Estimation on MIMO-OFDM Systems
نویسندگان
چکیده
Modern mobile telecommunication systems are using MIMO combined with OFDM, which is known as MIMOOFDM, to provide robustness and higher spectrum efficiency. One major challenge in this scenario is to obtain an accurate channel estimation to detect the information symbols, once the receiver must have the channel state information to equalize and process the received signal. The main goal of this paper is to present some techniques and analysis for channel estimation in MIMO-OFDM systems, considering the influence of various system parameters on the channel estimation error and on the final system performance.
