Restrained Latency Universal Modulator Outlay Adaptive CORDIC Algorithm for Digital Communication

Abstract

Digital communication plays a vital role in today’s communication system in this electronic world. However, the applications of digital communication are limited due to the requirements of antenna with fully programmable circuits having modulators and de-modulators. It may also end with hardware complexities. In order to overcome such complexities, a universal modulator is designed with an efficient iterative method named as CORDIC algorithm in prior methods. Although, the CORDIC (Coordinate Rotation Digital Computer) algorithm works efficiently, it leads to computational as well as memory complexities. Additionally it creates a need for latency reduction strategy. Therefore, to compete with all these issues faced with the prior method, we proposed an amended CORDIC algorithm in universal modulator working with the principle of the harmonized Stone–Weierstrass theorem. In addition, the Newton–Raphson method and Remz algorithm are introduced here to reduce the memory complexity by doubling the number of iterations and to select the best carrier signal, respectively. Thus, our proposed work effectively unravels all the notorious issues caused with the conventional CORDIC algorithm and the proposed universal modulator is implemented in Xilinx.
