EngeeComms.BPSKModulatorBaseband

Modulates data using the BPSK method.

Library	`EngeeComms`.
Block	BPSK Modulator Baseband

Description

The system object EngeeComms.BPSKModulatorBaseband modulates the signal using the binary phase shift keying (BPSK) method.

To BPSK modulate the signal, perform the following steps:

Create the object EngeeComms.BPSKModulatorBaseband and set its properties.
Call the object with arguments as if it were a function.

Syntax

Creation

bpskmodulator = EngeeComms.BPSKModulatorBaseband() creates a system object for binary phase shift keying (BPSK) signal modulation, with by default properties.

Example:
```
bpskmodulator = EngeeComms.BPSKModulatorBaseband()
```
bpskmodulator = EngeeComms.BPSKModulatorBaseband(Name=Value) creates a system object for modulating a signal using the Binary Phase Shift Keying (BPSK) method, with each specified property Name (name) set to the specified Value (value). You can specify additional arguments as a name-value pair in any order (Name1=Value1,…, NameN=ValueN).

Example:
```
bpskmodulator = EngeeComms.BPSKModulatorBaseband(PhaseOffset=pi/4)
```

Usage

waveform = bpskmodulator(data) applies BPSK modulation to the input data data and writes a BPSK modulated baseband signal to waveform.

Algorithms

Phase modulation is a linear baseband modulation technique in which the message modulates the phase of a constant amplitude signal. Binary phase shift keying (BPSK) is a biphase modulation scheme in which 0 and 1 in a binary message are represented by two different phase states in the carrier signal.

The basic representation of a BPSK signal is as follows:

The probability of a bit error in the AWGN channel is:
