MSK Modulator Baseband - Modulate using minimum shift keying method

Library

CPM, in Digital Baseband sublibrary of Modulation

Description

The MSK Modulator Baseband block modulates using the minimum shift keying method. The output is a baseband representation of the modulated signal.

The Phase offset parameter is the initial phase of the output waveform, measured in radians.

Input Attributes

The input can be either a scalar or a frame-based column vector. If the Input type parameter is set to Integer, then the block accepts values of 1 and -1. If the Input type parameter is set to Bit, then the block accepts values of 0 and 1.

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 Communications Blockset User's Guide.

Dialog Box

Input type: Indicates whether the input consists of bipolar or binary values.
Phase offset (rad): The initial phase of the output waveform.
Samples per symbol: The number of output samples that the block produces for each integer or bit in the input.
Output data type: The output type of the block can be specified as a single or double. By default, the block sets this to double.
