Improved MIMO Throughput With Inverse Power Allocation - Study Using USRP Measurement in Reverberation Chamber
Journal article, 2014
In this letter, we study the spatial multiplexing throughputs of multiple-input-multiple-output (MIMO) systems with fixed modulation and coding scheme (i.e., fixed peak rate) based on measurement of the universal software radio peripheral (USRP) in a reverberation chamber. In particular, we propose a simple inverse power allocation scheme for the singular value decomposition (SVD)-based MIMO system. Using the proposed power allocation, the power saving (for achieving the same throughput), compared to the SVD-MIMO without power allocation, is about 2.5 dB. Good agreement is observed between the USRP measurement and the simulation.
