Cooperative Orthogonal Space-Time-Frequency Block Codes over a MIMO-OFDM Frequency Selective Channel
In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...
متن کاملchannel 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...
Improved space-time coding for MIMO-OFDM wireless communications
Improved space–time coding for multiple-input and multiple-output orthogonal frequency division multiplexing is studied for wireless systems using QPSK modulation for four transmit and four receive antennas. A 256-state code is shown to perform within 3 dB of outage capacity (and within 2 dB with perfect channel estimation), which is better than any other published result without using iterativ...
متن کاملSpace Time Coding for Mimo Systems
With space-time codes (STC) the same information is transmitted in appropriate manner simultaneously from different transmit antennas to obtain transmit diversity. The main idea of transmit diversity is that if a message is lost in a channel with probability p and we can transmit replicas of the message over n independent such channels, the loss probability becomes p. Using diversity, more reli...
متن کاملHigh Rate Space-frequency Codes for Mimo-ofdm Systems
In the recent years, multiple-input multiple-out (MIMO) technology has attracted lots of attention because it significantly increases the data throughput (multiplexing gain) and link reliability (diversity gain) without additional bandwidth or transmission power. Orthogonal frequency division multiplexing (OFDM) technology has been developed into a popular scheme for wideband digital communicat...
