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 u...

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 ...

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 computin...
