Explanation for the following code in python
These 0 or 1 will get converted to -1 or 1 (0 $\rightarrow$ -1 , 1 $\rightarrow$ 1) so you will have BPSK modulated symbols. …

Bpsk demodulator implementation
For any digital communication scheme, the knowledge of carrier frequency (or the band it falls into) is a must. I think you meant carrier frequency for corner frequency. If you know this, next thing w …

Phase shifts of QPSK
In QPSK, the bit information is embedded in the phase of the carrier signal. For example, for bits 00, the phase shift is 45degree. This means the carrier signal $x(t) = cos(2\pi f_c t + \phi) 0 \lt …
