Dalam kertas kerja ini, prestasi pautan atas penerima Berbilang Input Berbilang Output Berbilang (MU-MIMO) Sifar Paksaan (ZF) disiasat berhubung saluran pudar Rayleigh yang berkorelasi dengan ralat anggaran saluran. Ungkapan matematik untuk Nisbah Isyarat kepada Bunyi (SNR) keluaran sub-aliran dengan korelasi hantar dan terima diperoleh dengan kehadiran anggaran saluran yang salah. Selain itu, ungkapan anggaran dan tepat untuk Kadar Ralat Bit (BER) penerima ZF untuk Modulasi Amplitud 16-Kuadratur (QAM) dengan korelasi hantaran disimpulkan dari segi fungsi hipergeometrik. Selepas itu, BER analitikal yang dibangunkan disahkan oleh jejak Monte-Carlo yang merangkumi pelbagai parameter sistem. Keputusan simulasi menunjukkan bahawa BER penerima ZF bergantung semata-mata pada korelasi penghantaran untuk bilangan antena penghantaran dan penerimaan yang sama pada nilai SNR purata yang lebih tinggi bagi setiap simbol yang dihantar (Es/N0). Juga, pertumbuhan logaritma dan eksponen dalam BER diperhatikan dengan peningkatan masing-masing dalam Ralat anggaran Mean Square (MSE) dan pekali korelasi.

Abstract: In this paper, the uplink performance of Multi-User Multiple Input Multiple Output (MU-MIMO) Zero Forcing (ZF) receiver is investigated over correlated Rayleigh fading channels with channel estimation error. A mathematical expression for the sub-streams' output Signal to Noise Ratio (SNR) with transmit and receive-correlation is derived in the presence of erroneous channel estimates. Besides, an approximate and accurate expression for the Bit Error Rate (BER) of ZF receiver for 16-Quadrature Amplitude Modulation (QAM) with transmit-correlation is deduced in terms of the hypergeometric function. Subsequently, the developed analytical BER is verified by Monte-Carlo trails accounting various system parameters. The simulation results indicate that ZF receiver's BER relies solely on the transmit-correlation for the same number of transmit and receive-antennas at higher average SNR values per transmitted symbol (Es/N0). Also, a logarithmic and exponential growth in the BER is observed with an increase in the Mean Square estimation Error (MSE) and correlation coefficient, respectively.
