Four Transmit Diversity Schemes for Coded OFDM Systems with Four Transmit Antennas
We compare four open-loop transmit diversity schemes in a coded Orthogonal Frequency Division Multiplexing (OFDM) system with four transmit antennas, namely cyclic shift diversity ...

Blind Cooperative Diversity Using Distributed Space-Time Coding in Block Fading Channels
— Mobile users with single antennas can still take advantage of spatial diversity through cooperative space-time encoded transmission. In this paper, we consider a scheme in whic...

Distributed one bit feedback extended orthogonal space time coding based on selection of cyclic rotation for cooperative relay n
In this paper, a novel closed-loop distributed extended orthogonal space time block code (D-EO-STBC) with one-bit feedback based on selection of phase rotation is proposed for two...

Improved High-rate Space-Time-Frequency Block Codes
— High-rate space-time-frequency block codes (STFBC) are promising for achieving high bandwidth efficiency, low overhead and latency. Recently, a class of low-complexity STFBC m...

The Performance of Coded Non-Coherent M-ary Orthogonal Keying Based OFDM Systems in a Frequency Selective and Fast Time-Varying
In this paper, we investigate the application of a unipolar Non-Coherent M-ary Orthogonal Keying (NC-MOK) for OFDM system that does not require channel estimation and compare its p...
