BPSK Modulator Baseband

Modulate using the binary phase shift keying method

Library

PM, in Digital Baseband sublibrary of Modulation

Description

The BPSK Modulator Baseband block modulates using the binary phase shift keying method. The output is a baseband representation of the modulated signal.

The input must be a discrete-time binary-valued signal. If the input bit is 0 or 1, respectively, then the modulated symbol is exp(j) or -exp(j) respectively, where is the Phase offset parameter.

Upsampling the Modulated Signal

This block can output 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.

Dialog Box

Phase offset (rad)

The phase of the zeroth point of the signal constellation.

Samples per symbol

The number of output samples that the block produces for each input bit.
