A Review to Massive MIMO Detection Algorithms: Theory and Implementation

Abstract: Multiple-input multiple-output (MIMO) systems entered most major standards in the past decades, including IEEE 802.11n (Wi-Fi) and long-term evolution (LTE). Moreover, MIMO techniques will be used for 5G by increasing the number of antennas at the base station end. MIMO systems enable spatial multiplexing, which has the potential of increasing the capacity of the communication channel linearly with the minimum of the number of antennas installed at both sides without sacrificing any additional bandwidth or pow… Show more

“…The problem of optimal and efficient wireless signal detection in a Multiple-Input, Multiple-Output (MIMO) system is central to this rapid growth and has been a key interest of network designers for several decades. While the optimal Maximum Likelihood (ML) detector is well known, it attempts to solve an NP-Hard problem [6] exactly, and so its implementation is usually impractical and infeasible for real-world systems. These computational challenges have prompted network designers to seek optimized implementations such as the Sphere Decoder [7], [8], or suboptimal approximations with polynomial complexity.…”

“…This is also due to the complex modulation techniques employed at the transmitter. Maximum Likelihood (ML) is the optimal decoding of received symbols in a MIMO channel, as it is capable of minimizing the probability of bit errors, but it is also known to be NP-hard [8], [9]. Today's commercial massive MIMO antenna systems already contain antenna arrays large enough to face complex decoding problem.…”

“… The performance of D2D-CRS-SM is analyzed and investigated, in terms of bit error rate (BER), spectral efficiency (SE), and sum SE considering M -PSK and M -QAM over independent Rayleigh fading channels. Moreover, comparative results with Vertical-Bell Laboratories layered space-time (VBLAST) spatial multiplexing MIMO technique [ 49 ] with zero-forcing (ZF) detector [ 50 ] (termed VBLAST-ZF) is also provided. The efficiency of D2D-CRS-SM is validated via Monte Carlo simulation.…”
