Design and Evaluation of a Multilevel Decoder for Satellite Communications
—In this paper, we propose a multilevel coding (MLC) scheme suitable for satellite communications, where different QoS levels are required. We introduce a novel characterization ...

Protograph LDPC Codes with Node Degrees at Least 3
— In this paper we present protograph codes with a small number of degree-3 nodes and one high degree node. The iterative decoding threshold for proposed rate 1/2 codes are lower...

Analysis and Design of Dirty Paper Coding by Transformation of Noise
— 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...

Performance analysis on LDPC-Coded systems over quasi-static (MIMO) fading channels
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...

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 ...
