In this contribution, we propose a Distributed Concatenated Irregular Convolutional Coded Unity Rate Coded and Space Time Trellis Coded (DC-IrCC-URC-STTC) scheme for cooperative communications employing multiple single-antenna relays. Each coding arrangement is designed for efficient decoding convergence by employing non-binary Extrinsic Information Transfer (EXIT) charts. The source node transmits...
In order to restrain the influence from atmosphere turbulence and channel time-varying character on free space optical communication system, a novel universal scheme with transmitting diversity and receiving diversity is put forward, into which STTC is introduced to fully make use of the characteristic of spatial diversity and time diversity. In order to reducing the decoding complexity, a modified...
Costa??s writing on dirty paper model is a power-limited system interfered by two independent noises, of which one is non-causally known by the transmitter. Considering the bandwidth of the channel is unlimited, we propose a new WDP co-decoding scheme based on trellis coded quantization and opportunistic pulse position modulation in which every pulse is sent when the transmitter-known noise reaches...
