— We design a coding scheme for Costa’s dirty paper coding (DPC) [6] using a channel and a shaping code. We show that by transforming the channel noise distribution the DPC cha...

In this paper, we derive closed form upper bounds on the error probability of low-density parity-check (LDPC) coded modulation schemes operating on quasi-static fading channels. Th...

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 ...
