Abstract

This thesis proposes a new decision rule for the space-time block (STB) coded wireless communication system in Rayleigh faded channel with partial knowledge of the channel state information (CSI). Also proposed is the frame-based iterative channel estimation algorithm for the same system with no knowledge of CSI. This thesis proposes a simpler modified decision rule which performs better in terms of bit error rate than the existing state-of-the-art technique using gray coded 16-QAM scheme with 2 transmitter antennas and 1 receiver antenna. The thesis also proposes the frame-based iterative channel estimator when no knowledge of CSI is available at the receiver. The algorithm exploits the inherent orthogonal property of the STB code. The BER performance reaches within 1 dB of the perfect knowledge of CSI for the simplest case with BPSK (Binary Phase Shift Keying) modulation having 2 transmitter antennas and 1 receiver antenna. The proposed algorithm outperforms the state-of-the-art iterative decision-directed channel tracking algorithm at the expense of increased receiver complexity.
