Space-time-frequency coded Multiple-Input and Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems have recently attracted much attention for broadband wireless communications including recent IEEE standards 802.11n and 802.16e. Space-time/Frequency Coding (SFC) can achieve the ...
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。
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...
Space–frequency coding and space–time–frequency (STF) coding are two types of the best schemes proposed for implementing MIMO–OFDM systems. By coding over multiple antennas and frequency tones, space-frequency block codes (SFBCs) use existing spatial and frequency diversities in frequency-...

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...

空时频移键控(ST-FSK)结合了空时分组码和频移键控的优点,在瑞利衰落信道条件下无需信道信息,可采用非相干的最大以然(ML)检测器。 Combining the advantages of space-time block codes and frequency keying, space-ti...
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 aspace-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,进行...
