To achieve 1000X improvements in capacity 5G communication networks integrate a heterogenous combination of advanced systems to increase data rate. A significant component of the improvement addressed in this paper network densification incorporates closely spaced radio access antennas to achieve high information rates. However 5G multi-user networks must cope with unprecedented levels of interference...
To achieve high data rates, reliable data rate transmission and near capacity performance for future wireless communication systems iterative processing has been widely considered. However, such an efficient receiver design has been made significant challenge. In this paper, multiple-input multiple output (MIMO) detection with channel decoding techniques has been investigated for achieve reliable...
In this paper, we studied the massive multiple-input multiple-output (MIMO) system performance with N antenna users and streams can be multiplexed per each user. The spectral efficiency (SE) of uplink and downlink expressions is derived for any N antenna users and these achievable using estimated channels and per user basis minimum mean squared error successive interference cancellation (MMSE-SIC)...
This paper, we evaluate the performance study of Long Term Evolution-LTE downlink with multiple input and multiple outputs (MIMO) system. MIMO transmissions schemes include transmit diversity and spatial multiplexing and MIMO detection schemes such as zero forcing and soft spheres decoding (SSD). The performance metrics considered are throughput and bit error rate (BER) and these are used to evaluate...

Multiuser MIMO (MU-MIMO) in which the base station transmits multiple streams to multiple users, has received significant importance as a way of achieving spectral efficiency (SE) and energy efficiency (EE). However, these two important design criteria conflict with each other and a careful study of their trade-off is mandatory for designing future wireless communication systems. This paper investigates...
In this paper, we investigate the performance of the low-complexity algorithms based on Likelihood Ascent Search (LAS) and Tabu Search (TS) for detection in MIMO systems with channel estimation errors. Here, we briefly review the algorithms for LAS and TS and their variants and subsequently compare them for various MIMO settings. We provide the simulation results for BER performance in 2× 2, 4× 4...
In this paper, we analysis the performance of Multiuser Multiple input Multiple output (MU-MIMO) Schemes in Long term evolution (LTE). As the performance metric, Block error rate and throughput are evaluated in terms of Signal to Noise Ratio (SNR) for different MIMO Schemes defined as in LTE. To achieve the high throughput required by the downlink LTE systems spatial multiplexing and transmit diversity...
In this paper, a power delay profile estimation technique for linear minimum mean square error channel estimator of Multi-User multiple-input multiple-output Orthogonal Frequency Division Multiplexing systems is proposed. For practical applications, the proposed technique uses only the pilot symbols of all the transmit antenna ports to estimate the power delay profile with low computational complexity...
