Abstract
This thesis considers a two-way relay system whereby two nodes exchange information
via a relay node. Amplify-and-forward (AF) is applied as a relaying strategy.The channel
information is not available at both receivers. The generalized likelihood ratio test (GLRT)
and least squares error (LSE) detectors are derived in order to achieve blind unique recovery
of the transmitted symbol. It is also proven that full diversity can be achieved. A constellation
selection algorithm is designed to optimize the symbol error rate (SER) performance.
This thesis also analyzes both theoretical procedures and simulation results of an existing differential
detection scheme for two-way relay channels. Monte Carlo simulations demonstrate
the performance of the proposed algorithm.
