Optimum Relay Selection in Cooperative Communication
Abstract: This paper is focused towards the relay selection scheme of cooperative diversity network. Log-likelihood Ratio (LLR) based relay selection scheme is applied to cooperative diversity architecture with cooperative non-regenerative (AF) relying technique. Bit Error Rate (BER) performance is compared using different fading environments

Literature Review of Spectrum Sensing in Cognitive Radio Networks
Abstract: The enduring growth of wireless digital communications and incredible addition of users has raised spectrum shortage and security issues in the last decade. In particular, the fixed spectrum allocation and non-availability of new bands in the spectrum is the main obstacle for the growth of wireless digital communications. The fixed spectrum allocation schemes makes spectrum inflexible for sharing.

Rake Receiver based MC-CDMA Scheme in Rayleigh Fading Channel using Different Equalization Techniques
Abstract: In this paper, we propose an MC-CDMA model using Rake Receiver and different equalization techniques (ZF, MMSE, EGC and MRC) are used. Rake receiver using different number of fingers has been considered for performance evaluation. Simulation has been carried out using MATLAB 2010a. Additionally, we examine its BER v/s SNR graph for different types of equalizers in Rayleigh fading channel. Simulation results show that the proposed technique outperforms existing multicarrier systems.

A Review of Different Clustering Protocols for WSN
Abstract: Wireless Sensor Network is collection of Sensors. Sensor nodes gather the sensory information and communicating with other nodes in networks. Key Challenges in Wireless Sensor Network is saving energy and extend the network life time. Many clustering protocol are used to manage the data transference in Wireless Sensor Network which are used in two types of network: Homogenous and Heterogeneous. The nodes having the same energy level are called Homogenous Network and the network having different energy level are Heterogeneous Network. Heterogeneous wireless sensor network (WSN) comprises of sensor nodes with distinctive capability, for example, diverse computing power and sensing range. Contrasted with homogeneous WSN, arrangement and topology control are more perplexing in heterogeneous WSN. This paper reviews about different clustering protocols for WSN.

Multiplier-Accumulator (MAC) Unit
Abstract: The MAC unit is a unit that is mostly demanded in DSP applications. MAC unit performs both multiply and addition functions. It operates in two stages. Firstly it computes the product of given numbers and forward the result for the second stage operation i.e. addition/accumulate. If both the computing is executed in a single rounding then it is said to be fused multiply-add/accumulate (MAC) unit. There has been a lot of research performed on MAC implementation. This paper provides a comparative study and analysis of the research and investigations held till now.
