With the exponential growth in the ways and means by which people need to communicate-data communications, voice communications, video communications, broadcast messaging, command and control communications, emergency response communications, etc. - modifying radio devices easily and cost-effectively has become business critical. Software defined radio (SDR) technology brings the flexibility, cost efficiency and power to drive communications forward, with wide-reaching benefits realized by service providers and product developers through to end users. Modern communications protocols are not simply streaming bits at 100% duty cycle. Instead, they use packets/frames. At the receiver, identification of frame is necessary when a new frame begins. Preamble contains a synchronization sequence that the receiver uses to detect start of frames, and it is a sequence known by the receiver beforehand. In this paper, frame synchronization using Barker Codes (BC) for various Frame Length (FL) (taken frame lengths are 3,4 and 13) by applying different modulation techniques like Binary Phase Shift Keying(BPSK) and Quadrature Phase Shift Keying (QPSK).
