In this paper, we analyze the ergodic spectral efficiency upper bound of large-scale MIMO, and key technologies including channel uplink detection. We also present new approaches for detection and power allocation. Assuming arbitrary antenna correlation and user distributions, we derive approximations of achievable rates with linear detection techniques, namely Zero Forcing (ZF), Maximum Ratio Combining (MRC), Minimum Mean Squared Error (MMSE) and Eigen-Value Decomposition Power Allocation (EVD-PA).The approximations are tight in the large system limit with an infinitely large number of antennas and user terminals (UTs), but match our simulations for realistic system dimensions. We further show that a simple EVD-PA detection scheme can achieve the same performance as MMSE with one order of magnitude fewer antennas in both uncorrelated and correlated fading channels. Our simulation results show that our proposal is a better detection scheme than the conventional scheme for LSAS. Also, we consider the use of two channel environment channels for further analysis of our algorithm given as Long Term Evolution Advanced (LTE-A) and Millimeter wave Mobile Broadband (MMB) channel.
