Abstract :
This paper considers the Multiple Input Multiple Output (MIMO) capacity enhancement considering the Universal Mobile Telecommunication System (UMTS) Long Term Evolution (LTE) technology, in the downlink, including the effects of system bandwidth and Signal-to-Noise Ratio (SNR) efficiency. Firstly, the system bandwidth efficiency is calculated for LTE framework. Then, the SNR efficiency using Adaptive Modulation and Coding (AMC) is approximated using curve fitting. The used fitting function is an attenuated and truncated form of the Shannon bound in order to approximate the LTE composite spectral efficiency for the Modulation and Coding Set (MCS). Finally, the total capacity expected results are calculated for different multi-antenna configurations, revealing large capacity gains when compared with Single Input Single Output (SISO).
