Channel estimation is an essential task in MIMO-OFDM systems for coherent demodulation and data detection. Also designing pilot tones that affect the channel estimation performance is an important issue for these systems. For this reason, in this article we propose particle swarm optimization (PSO) to optimize placement and power of the comb-type pilot tones that are used for least square (LS) ...
Optimal pilot assisted estimation of communication channels is considered for coherent cellular and PCS CDMA reverse link communications. Both pilot symbol and pilot channel based schemes are described and the optimal estimators for these two schemes are analyzed. Relative mean square estimation error (RMSEE) and optimal power allocation between data and pilot signals are derived based on the a...
Small-scale pilot projects have demonstrated that integrated population, health and environment approaches can address the needs and rights of vulnerable communities. However, these and other types of health and development projects have rarely gone on to influence larger policy and programme development. ExpandNet, a network of health professionals working on scaling up, argues this is because...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
This article describes the results of one of the ten pilot programmes under the Integrated Manufacturing and Service Systems (IMSS) initiative pursued by the Agency for Science, Technology and Research (A*STAR) in Singapore. The objective of this particular programme is to investigate how design, analysis, enhancement and implementation of critical business processes in a manufacturing and serv...
