channel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Quantization Design and Channel Estimation for Massive MIMO Systems with One-Bit ADCs
We consider the problem of channel estimation for uplink multiuser massive MIMO systems, where, in order to significantly reduce the hardware cost and power consumption, one-bit analog-to-digital converters (ADCs) are used at the base station (BS) to quantize the received signal. Channel estimation for one-bit massive MIMO systems is challenging due to the severe distortion caused by the coarse...
متن کاملOne-Bit Sphere Decoding for Uplink Massive MIMO Systems with One-Bit ADCs
This paper presents a low-complexity near-maximum-likelihood-detection (near-MLD) algorithm called one-bit-sphere-decoding for an uplink massive multiple-input multiple-output (MIMO) system with one-bit analog-to-digital converters (ADCs). The idea of the proposed algorithm is to estimate the transmitted symbol vector sent by uplink users (a codeword vector) by searching over a sphere, which co...
متن کاملThroughput analysis of massive MIMO uplink with one-bit ADCs
Massive MIMO is a disruptive technology that consists of equipping communication transceivers with an excessive number of antennas to enable unprecedented gains in throughput and radiated energy efficiency. From an industry perspective, massive MIMO will happen only if the required large antenna arrays can be built out of low-cost (and, hence, low-precision) components. Therefore it is of inter...
متن کاملMessage passing-based joint CFO and channel estimation in millimeter wave systems with one-bit ADCs
Channel estimation at millimeter wave (mmWave) is challenging when large antenna arrays are used. Prior work has leveraged the sparse nature of mmWave channels via compressed sensing based algorithms for channel estimation. Most of these algorithms, though, assume perfect synchronization and are vulnerable to phase errors that arise due to carrier frequency offset (CFO) and phase noise. Recentl...
