Analysis and implementation of minimum shift keying (MSK) modulation on FPGA platform

Most of the communication techniques for telemetry applications are analog modulation techniques like PCM/FM in earlier years. Increased data rates and increased number of platforms requires more bandwidth efficient modulation techniques to avoid losses, interferences in information transfer. MSK has been introduced as part of continuous phase modulation technique and more bandwidth efficient technique as well. Telemetry is an automated communications process by which measurements and other data are collected at remote or inaccessible points and are subsequently transmitted to receiving equipment for monitoring. Motivation and an objective behind study of MSK scheme is described with an overview of digital modulation schemes. This paper is an exclusive analysis and implementation of MSK modulation technique on FPGA platform. Simulation results of MSK modulation technique are verified with implementation of same on Xilinx virtex-4 FPGA board.
