Linear precoder optimization of spectral efficiency of time division duplex hyper MIMO system with pilot contamination

Our work is developed in context of studing Massive MIMO a 5G context. The aim to optimize spectral efficiency several users hyper system during Uplink communication multi-cell contaminated pilot environment, using new type precoders called single cell-minimum mean square eroor (S-MMSE) and multicell-minimum (MMMSE). Indeed, we address two key well-known issues massive multiuser (MU-MIMO) environments test-driven development (TDD) operation scheme, namely acquisition uplink channel state information (UL) optimisation the bit stream per unit frequency, (SE). From practical point view, these notions are inclusively linked. very good estimation leads better efficiency. In our approcah, derive from minimum error estimator (MMSE) types that can operate multicell environment with sequence, SMMSE M-MMSE. A comparative study performance classical such as regulated zero forcing (RZF), ZF (Zero Forcing) MR (Minimum Ratio) encountered multi-antenna processing shows an improvement nearly 51% terms gain
