Abstract: In wireless communications, spectrum is a scarce resource and hence imposes a high cost on the high data rate transmission. It has been demonstrated that multiple antenna system provides very promising gain in capacity without increasing the use of spectrum, reliability, throughput, power consumption and less sensitivity to fading, hence leading to a breakthrough in the data rate of wireless communication systems The vertical Bell labs layered space-time (V-BLAST) system is a multi-input multi-output (MIMO) system designed to achieve good multiplexing gain.. In this paper, we study the V-BLAST MIMO system architecture, with optimally ordered successive interference cancellation (SIC) receiver in ZERO FORCING EQUALIZATION (ZF) and simulate this structure in Rayleigh fading channel. Based on bit error rate, we show the performance of this receiver, indicates that the ordered SIC detector most effectively balances the accuracy of symbol detection. SIC receiver based on ZF combined with sy

Abstract: Service Oriented Software Engineering is the most promising engineering paradigm in industry now-a-days. It focuses on development of software systems based on reusable services that can distributed in nature. Migrating legacy system developed in any language to Service Oriented Paradigm is in trend now. Enterprises have more powerful software with lesser cost. There has always been a difference between the methods of migration proposed by academia and as used in industry. Academia suggests that while migration, legacy system should be reverse engineered. But in practice, legacy systems are forward engineered. The paper tries to fill the agreement gap between Industry and Academia upon the migration of legacy system to SOA system. In this research, Memory and CPU utilization of various events of legacy system, Forward Engineered SOA system, and Backward Engineered SOA system were recorded. Recommendation is given that migration technique should be chosen by keeping these trade-offs in
