The memories are more and more used as an embedded element rather as a separate block. Being used as a macro, its user has nothing to change or optimize. So, the design of memory needs to address all the issues specially to optimize the rigorous area and power requirements. This paper discusses the issues in design of SRAM memory cell for low power applications. 6T architecture SRAM cell is taken...
In this paper, we propose a low-complexity algorithm based on Markov chain Monte Carlo (MCMC) technique for signal detection on the uplink in large scale multiuser multiple input multiple output (MIMO) systems with tens to hundreds of antennas at the base station (BS) and similar number of uplink users. The algorithm employs a randomized sampling method (which makes a probabilistic choice between...
SMS has a variety of advantages and disadvantages for M-Commerce purpose. The advantages are it is easy to use, a common messaging tool among consumers, works across all wireless operators, affordable for mobile users, no specific software required for installation, allows banks and financial institutions to provide real-time information to consumers and employees and stored messages can be accessed...

MIMO systems with large number (tens) of antennas are getting increased attention. In particular, low-complexity near-optimal detection in such large-MIMO systems has been an interesting topic of recent research. In this context, our new contributions in this paper are two-fold. First, we propose a variant of Markov chain Monte Carlo (MCMC) algorithm which i) alleviates the stalling problem encountered...
