This paper considers wideband extensions of narrowband signal processing techniques for MIMO wireless transceivers. The extensions are applied and analyzed on commonly used wideband systems such as W-CDMA and OFDM. The paper focuses on signal processing techniques for channel estimation and correction, including pilot-aided and decision-directed LMS-based adaptive estimation. Simulation study compares cases with one and two transmit/receive antennas and shows that BER of W-CDMA system consistently improves by exploiting multi-path diversity through additional antenna at the receiver, while additional transmit antenna is beneficial under specific channel conditions.
