Enhanced parity packet transmission for Video multicast using R-DSTC
In this paper, a cooperative multicast scheme that uses Randomized Distributed Space Time Codes (RDSTC), along with packet level Forward Error Correction (FEC), is studied. For the...

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 ...

Physical Layer Differential Network Coding for Two-Way Relay Channels
— In this work, we consider differential modulation in two-way relay channels (TWRC). In single antenna systems, we propose non-coherent schemes for both amplify-and forward (AF)...

Square Complex Orthogonal Designs with Low PAPR and Signaling Complexity
Abstract--Space-Time Block Codes from square complex orthogonal designs (SCOD) have been extensively studied and most of the existing SCODs contain large number of zero. The zeros ...
