Performance Analysis of 1-Bit Massive MIMO with Superimposed Pilots
In this work, we consider a 1-bit quantized Massive MIMO channel with superimposed pilots (SP), dubbed “QSP”. With linear minimum mean square error (LMMSE) channel estimator and maximum ratio combining (MRC) receiver at the BS, we deive an approximate lower bound on the ergodic achievable rate. When optimizing pilot and data powers, the optimal power allocation maximizing the data rate is obtai...
متن کاملMassive MIMO with 1-bit ADC
We investigate massive multiple-input-multipleoutput (MIMO) uplink systems with 1-bit analog-to-digital converters (ADCs) on each receiver antenna. Receivers that rely on 1-bit ADC do not need energy-consuming interfaces such as automatic gain control (AGC). This decreases both ADC building and operational costs. Our design is based on maximal ratio combining (MRC), zero-forcing (ZF), and least...
متن کاملAnalyze of Pilot Reuse with Achievable Sum Rate for Massive Mimo Cellular Uplink
The last ten years have seen important developments of massive multi-input multi-output (MIMO) in wireless communication. Massive MIMO has currently been presented in the 5G wireless standards. The number of terminals is increasing with additional appliances. At the same time, high transmission sum rates and communication reliability are required. Moreover, the multi-cell MMSE scheme, which inc...
متن کاملAchievable Rate Performance of TDD Multi-cell Massive MIMO with Non-Orthogonal Pilots
Massive multiple-input multiple-output (MIMO) is a promising technology that provides high system capacity, and with excellent performance in energy efficiency and system robustness. However, pilot contamination restricts the system performance due to the limited length of orthogonal training sequences. In this paper, we propose optimization of nonorthogonal pilots for uplink training. The Gras...
متن کاملMassive Connectivity with Massive MIMO-Part II: Achievable Rate Characterization
This two-part paper aims to quantify the cost of device activity detection in an uplink massive connectivity scenario with a large number of devices but device activities are sporadic. Part I of this paper shows that in an asymptotic massive multiple-input multiple-output (MIMO) regime, device activity detection can always be made perfect. Part II of this paper subsequently shows that despite t...
