SMT-8036 based implementation of secured software defined radio system for adaptive modulation technique

Abstract

In this paper, we present the implementation and verification of an secured adaptive modulation system on a Software Defined Radio (SDR) development platform. The SDR platform is supported by highly productive development system emphasizing the value of a structured development process that takes the developer through modeling, system analysis, implementation and verification by bit error rate analysis. SDR platform is a massively parallel processor in which transmitter and a part of receiver is implemented on DSP processor and demodulator is implemented on FPGA. For adaptive modulator-demodulator architecture, a bit error rate analysis is presented. Result shows that for same BER, BPSK requires minimum SNR. © 2011 Springer-Verlag.
