Summary:
In this paper, Equal Gain Combining (EGC) technique is considered because it provides performance comparable to the optimal Maximal ratio combining (MRC) technique but with greater simplicity. Although, performance evaluation of EGC diversity is a much more difficult task in comparison with other classical techniques but it has been presented several times in literature. However, the problem concerning multiple antennas on limited space has never been presented. This is because the correlation between multiple antennas can be neglected if the antenna spacing is large enough. In practice, the dimension of user terminal is fixed with the trend of small in size. Therefore, it is impossible to avoid the effect of antenna correlation due to limited space. In this paper, the performance investigation of EGC diversity technique is presented by considering the problem of multiple antennas on limited space. The simulation results reveal the significant differences observed if neglecting the antenna correlation.
