Performance and Analysis of MIMO Multichannel Beamforming under the Double Scattering Channel
Abstract
We present the new method to investigate and analyze the symbol error rate performance of the multiple-input multiple-output (MIMO) multi-channel beam forming (MB) under the double-scattering channel. In the proposed method we derive an asymptotic expansion on the marginal eigen-value distribution of the MIMO channel matrix, and use the result to obtain an approximate expression on the average SER at high signal-to-noise ratio (SNR).Two major parameters of the SER, i.e., the diversity gain and the coding gain are analyzed. Our simulation results explain that it suffices for the double-scattering channel to have only limited scatterers, if the same diversity gain as the Rayleigh channel is desired; however, when the number of scatterers is below a certain level, the codinggain in the double-scattering channel will vary with the SNR logarithmically.
