Summary:Title screen
A new methodology for lossy forwarding based on a novel technique known as soft angular modulation is investigated. In this new relay (R) scheme, the soft symbols are embedded into phases at the R. This is more advantageous as to forward real values (under bandwidth constraints) via wireless channels is refrained. This makes the proposed scheme practically feasible. The proposed system provides a means of using distributed low-density parity-check coding. This also precludes the amplitudes of generated symbols descent to zero, as happens with most of the existing soft forwarding (or lossy) methods. Ordinarily, such schemes suffer from error propagation to the destination when the signal-to-noise ratio of the source (S)-R link is low; however, the system avoids this problem by regenerating soft versions of the S symbols at the R. Simulation results demonstrate that the proposed scheme can maintain very good performance.
