Python source code is available for download. http://www.wu.ece.ufl.edu/projects/softwareRadio/ I see that your project is under the … WebBinary phase-shift keying (BPSK), also known as bi-phase modulation, is a simple, popular digital modulation scheme. The symbol constellations are as far apart as possible, which is desirable for weak signal work. BPSK is also popular for its relatively simple spectrum-spreading capability.

WebPrinciple of BPSK. BPSK technique is the simplest among all the PSK techniques. In this, each signalling element is represented by a single data bit. Here, the carrier undergoes two phase reversal such as 0° and 180°. In phase shift keying the digital bit sequence is first converted to NRZ bipolar signal which directly modulates the carrier wave.
