To improve the adaptability of a receiver based on the Cauchy distribution, the myriad filters have been discussed in [20,92,99]. They are based on the Cauchy density but with a modified dispersion parameter\(\kappa\)replacing\(\gamma\)in (13) so that the decision rule becomes: $$\begin...
As increasing the code rate is limited by the hardware capacity, we provide some guidelines to optimize the LDPC codes implementation (Section 3.7). Modeling of the average waiting time for any forwarder. The finding is interesting: selecting the first awake forwarder (independently of the progress...
Simulation results illustrate that the constructed D-LDPC codes exhibit significant performance improvement and enhanced flexible frame length (i.e., adaptability under various channel conditions) compared with the benchmark code pair. Keywords: joint source-channel coding; low-density parity-check code;...
