Abstract
This paper introduces a new pilot pattern which is obtained by using NRZ Encoder. By using the proposed NRZ Encoded Pilots for Semi Blind Channel estimation (in which the channel response is obtained by interpolating the subsequent channel estimations) in MIMO-OFDM, reduces the Mean Square Error for moderately varying channels and reduces complexity. This method perfectly utilizes the bandwidth and improves the system performance by accurate channel estimation compared to pilot based channel estimation.
