| Abstract: | Antenna diversity techniques can be used to improve the performance of a wireless communication system. Three new antenna diversity schemes, namely, multi-selection diversity, inverted multi-selection diversity, and extended inverted multi-selection diversity are proposed in this paper. These schemes only require a minimal RF hardware complexity. Simulation results showed that a significant signal to noise ratio (SNR) gain could be achieved by using these schemes compared to using traditional selection diversity techniques in certain cases. |
