Current multi-user detection scheme for sparse code multiple access (SCMA) is iterative message passing algorithm (MPA) in which the message update strategy is in a parallel manner. To take full advantage of MPA's feature of parallelism, this letter proposes a hardware implementation strategy of max-log MPA decoder used in SCMA systems with soft baseband, which is based on general-purpose computing...
Proposed is a blind recognition method for Bose–Chaudhuri–Hocquenghem (BCH) codes in the faster-than-Nyquist (FTN) signalling system which is based on the Galois field Fourier transform of the code polynomial. Considering the signal-to-noise ratio estimation in coloured noise, the proposed method can maximise the correct recognition probability of the roots of the generator polynomial by an appropriate...
We investigate the design and use of systematic binary deterministic rateless (BDR) codes for information transmission over block-erasure broadcast channels. BDR codes are designed to obtain a level of maximal distance separable (MDS) properties, making these codes ideal for the considered broadcast scenario. For a certain number of encoded redundancy blocks, we derive an expression for the probability...
Applying estimation of distribution algorithms (EDAs) to solve continuous problems is a significant and challenging task in the field of evolutionary computation. So far, various continuous EDAs have been developed based on different probability models. Initially, the EDAs based on a single Gaussian probability model are widely used but they have trouble in solving multimodal problems. Later EDAs...
Many high-performance DSP processors employ multi-module on-chip memory to improve performance and power consumption. This paper studies the scheduling and assignment problem that minimizes the total energy while satisfying performance for applications with loops. An algorithm, LSAMEM (Loop Scheduling and Assignment to Minimize Energy for Memory), is proposed. The algorithm attempts to maximum energy...
In order to prevent the malicious attack from reducing the accuracy of aggregation result in wireless sensor networks, it is necessary to perform the attack detection in the received readings of all the sensor nodes before the resilient aggregation processing. However, the detection probability of the attack detection algorithm presented in the literature is small, and its computation complexity is...
In this paper, the outage probability of space-time coded decouple-and-forward (DCF) relay network in Nakagami-m fading channels is analyzed. We derive both accurate expressions and closed-form bounds of outage probability by investigating the statistic property of sum of Gamma random variables. All the analytical results are confirmed through Monte Carlo simulations.
