摘要原文 We consider the capacity of multiple-input-multiple-output (MIMO) systems that use OFDM as the modulation format. We point out a basic equivalence between antennas and OFDM-tones. This similarity immediately allows us to essentially reuse all space-time codes designed for flat-fading chan...
A space-time-frequency block coding scheme for orthogonal frequency division multiplexed (OFDM) systems is derived. 提出了一种空时频分组编码方案,其设计思路是:接收端通过子信道的相关特性确定不相关子载波组,并反馈给发射端;发射端基于反馈信息,利用星座旋转预编码矩阵和空时分组编码技术构建空时频分组编码。

To enhance the multiple interference suppression performance of global navigation satellite system (GNSS) receivers without extra antenna elements, a space-time-frequency adaptive processor (STFAP) is investigated. Firstly, based on the analysis of the autocorrelation function of the multicomponent signal,...
We propose a linear mean square error channel estimator that exploits the joint space-time- frequency (STF) correlations of the wireless fading channel for applications in multiple- antenna orthogonal frequency division multiplexing systems. Our work generalizes ex...
The achievement of our previously proposed space–time coding algorithm entitled full-rate linear-receiver space–time block code (FRLR STBC) has motivated us to propose, in this paper, a new class of high-rate space–time–frequency block codes (STFBCs) over frequency-selective Rayleigh fading...
We study the impact of space-time-frequency processing techniques on the physical layer performance of an orthogonal frequency division multiplexing (OFDM) based wireless LAN (IEEE 802.11a/g). A space frequency code (SFC) with two different soft-input soft-output multiple antenna receivers is compa...
1) space-time-frequency spreading 空时频扩频1. STS is expanded from a single carrier to multi-carrier when space, time and frequency are coded, which results in a space-time-frequency spreading(STFS) coding arithmetic. 通过一种空时频扩频(STFS)的编码算法,将单载波的空时扩频扩展到多载波,...
Space-Time Shift Keying (STSK) modulation, in this paper we proposed the Space-Frequency Shift Keying (SFSK) modulation as well as the Space-Time-Frequency Shift Keying (STFSK) concept which spreads the transmit signal not only across the space and time domains, but also the frequency domain...
