Appendix D

Derivation of the Average Pairwise Error Probability

There are several methods to evaluate the average PEP of space-time codes. In the sequel, we present a method based on Craig’s formula that has been extensively used in [SA00, Sim01] because of the simplicity of its derivation. Other methods can be found in [UG01, UG04, TB02].

When a codeword image is transmitted through image antennas, we are interested in the probability that a ML decoder decodes the codeword instead of codeword . This probability is known as the Pairwise Error Probability ...
