Implementation of TAS in MIMO Using Software Defined Radio

摘要

Multiple Input Multiple Output (MIMO) systems are used in recent wireless communication systems due to diversity benefits. At the cost of performance degradation, complexity of hardware associated with radio frequency front end is reduced with antenna selection. TAS techniques are more popular in MIMO system as they provide the benefit of reduced hardware. The recent literature verifies the performance of the TAS systems analytically and on simulation platform. In this paper, the practical implementation of TAS-MIMO system is proposed using Software Defined Radio (SDR). The TAS-MIMO system is implemented to create an on-field environment for transmitting the signals over the channel. This paper validates the analytical results with the practical hardware implemented using SDR for different MIMO configurations.
