摘要：
In this paper we study the joint estimation and compensation of Channel Impulse Response (CIR) and Phase Noise process in MIMO-OFDM systems. The proposed scheme is a semi-blind (SB) channel estimation scheme. This scheme uses blind data and equally spaced pilots to estimate channel. The joint channel and PN estimation is done iteratively. To assess the performance of our scheme we derive the Cramer-Rao Lower Bound (CRLB) for MIMO-OFDM with partial training. Simulation results show that proposed scheme performs well at low and moderate SNR.
