Abstract In the past decade, spatial modulation was introduced as a multiple-input multiple-output system. Essentially, spatial modulation aims to enhance the power efficiency, reduce the error rate and the complexity at the receiver, and eliminate the inter-channel interference. However, spatial modulation suffers from a required dramatic increase in the number of transmit antennas to achieve a slight improvement in spectral efficiency. In this thesis, we propose two spatial schemes, namely, the fully generalized spatial modulation utilizing transmit antenna grouping and power-arranged generalized spatial modulation schemes. The goal of the two proposed schemes is to improve the spectral efficiency and average bit error rate of the system. The first proposed scheme, the fully generalized spatial modulation scheme utilizing transmit antenna grouping, utilizes the idea of dividing the transmit antennas into groups. Then, the different data bits from all the groups are to be multiplexed and simultaneously transmitted to the receiver. |
