Offset Shuffle Networks (OSNs) interleave a-posterior probability messages in the Block Row-Layered Decoder (BRLD) of Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) codes. However, OSNs usually consume a significant amount of computational resources and limit the clock frequency, particularly when the size of the Circulant Permutation Matrix (CPM) is large. To simplify the architecture of the OSN,...
In this paper, we proposed a measurement-based admission control (MBAC) algorithm for adaptive real-time applications. In our algorithm, admission test is performed over successive time scale (STS) by an iterative manner. Analysis and simulation results show that STS algorithm obtains consistency and robustness by capturing the burstiness over multiple time scales exactly, and achieves high bandwidth...
In this paper, two reduced-complexity timing detectors for MC-CDMA signals based on incorporating the on-time arm in timing error signal update are proposed and analyzed. By theoretical analysis and simulations, it is shown that the simplified approaches provide superior performance for low Eb/N0 with respect to the classical non-coherent early-late gate detector
