Abstract

The paper presents the outage probability and the Average Bit Error Rate (ABER) for a Multiple-Input Multiple-Output (MIMO) system over generalized-fading channel. Transmit antenna selection at the base station is performed and Maximal Ratio Combining (MRC) at the receiver is considered for the downlink transmission. The antenna at the transmit end that maximizes the instantaneous output Signal-to-Noise Ratio (SNR) is selected for transmission. The effect of fading parameters on the performance of the system has been observed analytically. The effect of the number of transmit and receive antennas on the system has been studied. Computer simulations are performed to assess the accuracy of the proposed mathematical analysis.


Description

In wireless communication, a channel may experience fading. Fading occurs due to multiple transmission paths, irregularities of earth surfaces or varying terrains or from man-made disturbances such as buildings or concrete walls, etc. As a result, the receiver perceives multiple copies of transmitting signal. Each signal copy will experience differences in attenuation, delay and phase shift which cause the received signal to fluctuate.
