Naresh Journal on Electronics Engineering 2249 – 0760 6 4 18 23 Iterative Methods, Sparse Structure, Code Division Multiple Access (CDMA) System, Parallel Interference Cancellation, Multiple Access Iterative methods are the basic building blocks of communication systems and represent a dominating part of the system. So, it is necessary for the careful design of the system for optimal performance. The most computationally expensive operations in the iterative methods are the matrix-vector multiplications. Therefore, it is important to reduce the number of matrix-vector multipliers in the design to reduce the hardware consumption. In this paper, the authors have proposed a design of matrix-vector multiplier that can be used to implement the widely adopted iterative methods. By using Brent Kung adder, the computational performance is increased by reducing the hardware consumption. The proposed design uses the sparse structure of the matrix and the spreading code matrices have equal magnitude entries. The design and simulation results are promising and are shown to satisfy the most modern communication system requirements. June – August 2016 Copyright © 2016 i-manager publications.
