BPSK Demodulator Baseband

Demodulate BPSK-modulated data

Library

PM, in Digital Baseband sublibrary of Modulation

Description

The BPSK Demodulator Baseband block demodulates a signal that was modulated using the binary phase shift keying method. The input is a baseband representation of the modulated signal. The input can be either a scalar or a frame-based column vector.

The input must be a discrete-time complex signal. The block maps the points exp(j) and -exp(j) to 0 and 1, respectively, where is the Phase offset parameter.

Processing an Upsampled Modulated Signal

The input signal can be an upsampled version of the modulated signal. The Samples per symbol parameter is the upsampling factor. It must be a positive integer. For more information, see Upsampled Signals and Rate Changes in Using the Communications Blockset.
