Introduction to the special issue on Recent trends in communications and signal processing Communication systems and devices are essential parts of many people’s life around the globe today. The world now is more inter-connected than ever before, and this will continue. Signal processing plays a key role in communications. The explosion of smart-phones and tablets usage in recent years provides end-users with communication and computational capabilities anywhere and anytime. Moreover, the demand for higher bandwidth in wire-line and wireless communication sectors from mass market, small and medium businesses, and large enterprises is growing. As a result, extensive research has been ongoing in all communication layers in both industry and academia. This special issue includes a selection of revised and extended versions of papers from the Second International Conference on Communication and Signal Processing (ICCSP 2013), which was held at Adhiparasakthi Engineering College, Melmaruvathur, Tamil Nadu, India, from April 3rd to April 5th 2013. Authors of papers which received the best review comments from the conference were provided an opportunity to submit extended and revised versions of their paper for potential publication in this special issue. Out of the 9 submitted papers, 6 papers were selected through the regular review process of CAEE. A similar special issue consisting of extended versions of papers from the First International Conference on Communication and Signal Processing (ICCSP 2012) was published in CAEE in April 2013 (Volume 39, Issue 3). The first paper by B. Nancharaiah and B. Chandra Mohan proposes a novel routing algorithm for mobile ad hoc network by combining two meta-heuristic optimization techniques – Ant Colony Optimization (ACO) and Particle Swarm Optimization (PSO). Performance analysis of the proposed algorithm by comparing it with ACO is presented, and the results show that the proposed algorithm performs better than ACO with respect to communication cost, power consumption, and delay. The next paper by Saha et al. uses a meta-heuristic optimization technique, harmony search algorithm, to derive optimal sets of filter coefficients for infinite impulse response filters. Extensive performance analysis by comparing the proposed method with other meta-heuristic optimization techniques like PSO algorithm, differential evolution algorithm, and real coded genetic algorithm is presented, and the results show that the proposed algorithm is effective and efficient. The third paper by Nagarajan Velmurugan and S. Muthukumar proposes a new diversity combining scheme for cooperative diversity systems, switched selection combining technique, which combines the ideas of switched diversity and selection combining. The authors compare and show that the proposed technique performs better than selection combining and non-cooperative schemes. The next paper by Vishvaksenan et al. uses a dual-polarized antenna for down link communication in a multi user environment in double space–time transmit diversity interleave division multiple access system. The performance results show that using dual-polarized antenna does not perform better than using uni-polarized antennas, but reduces the number of antennas required. The fifth paper by Murali et al. investigates the performance of a relay aided down link direct sequence code division multiple access system using multi-user transmitter preprocessing (MUTP), which is realized using perfect channel impulse response (CIR), vector quantized (VQ) CIR, and, noise and fading contaminated VQ-CIR. The results show the attainable bit error rate with MUTP using VQ-CIRs acquired by ideal feedback provide same performance as perfect CIR. On the other hand, the bit error rate performance of the noise and fading affected VQ-CIRs is poor compared to the other two CIRs. The last paper by Nagaradjane et al. investigates the performance of MUTP assisted down link space-division multiple access system. The results shows that MUTP realized with perfect CIRs eliminates Multi-User Interference (MUI), but VQchannel spatial information based MUTP does not perfectly remove the MUI, and the performance further degrades when contaminated with noise and fading. However, VQ-channel spatial information with ideal feedback provides comparable performance as perfect CIR.
