碩士 === 國立清華大學 === 電機工程學系所 === 106 === In this thesis, we derived a simple diversity-multiplexing tradeoff of a space-time coding scheme for linear modulation over frequency-nonselective fading channels. With an optimal convolutional temporal encoder and the Golden spatial code, which achieves the full transmit spatial diversity, the maximum overall diversity gain is Lr*Lt*ECL over fast fading channels, where Lr is the number of receive antennas, Lt the number of transmit antennas, ECL the effective code length of the convolutional encoder. With the Viterbi decoder, simulation results demonstrate the theoretical analysis and justify the effectiveness of our coding scheme.
