Transmitter

Signal amplification and transmission.

blockType: Transmitter

Path in the library:

/Phased Array Systems/Transmitters and Receivers/Transmitter

Description

Block Transmitter amplifies and transmits waveform pulses. The transmitter can maintain coherence between pulses or introduce phase noise.

Ports

Entrance

Input 1 — incoming signal
the complex matrix

The size of the first dimension of the input matrix can be varied to simulate a changing signal length. A change in size may occur, for example, in the case of a pulse signal with a variable pulse repetition rate.

Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, UInt8, UInt16, UInt32, UInt64, Bool

Output

TR — pass transmitter on/off status:q[<br>] 0 | 1

The status of the transmitter.

1 indicates that the transmitter is on.
0 indicates that the transmitter is turned off.

Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, UInt8, UInt16, UInt32, UInt64, Bool

Dependencies

The port is enabled when the Enable transmitter status output checkbox is selected.

Ph — phase noise
scalar

Phase noise for each input sample X, output signal as a scalar.

Dependencies

The port is enabled when the Enable pulse phase noise output checkbox is selected.

Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, UInt8, UInt16, UInt32, UInt64, Bool

Y — pass output signal:q[<br>] the complex matrix

The output signal returned as a complex matrix.

Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, UInt8, UInt16, UInt32, UInt64

Parameters

Peak power (W) — peak power
5000 (default)| positive scalar

Set the peak transmission power (in watts) as a positive scalar quantity.

Gain (dB) — gain of the pass transmitter:q[<br>] 20 (default) | the real scalar

Specify a scalar containing the transmission gain (in dB).

Loss factor (dB) — pass loss factor:q[<br>] 0 (default) | a non-negative scalar

Specify a non-negative scalar containing the transmission loss coefficient (in dB).

Enable transmitter status output — enable the output of the transmitter status
disabled (by default) | enabled

Select the checkbox to display the status of the transmitter usage for each output sample from the output port TR.

Preserve coherence among pulses — preserve the coherence of transmitted pulses
enabled (by default) | turned off

Select this option to maintain the coherence of the transmitted pulses.

When you select this field, the transmitter does not add random phases to the output pulses.
When you clear this field, the transmitter adds random phase noise to each transmitted pulse. Random phase noise is introduced by multiplying the pulse value by , where — a homogeneous random variable in the interval .

Enable pulse phase noise output — enable pulse phase noise output
disabled (by default) | enabled

Check this box to create a Ph output port with random phase noise of the output sample, if the Preserve coherence among pulses checkbox is unchecked. The output port can be directed to the receiver to simulate coherent systems on reception.

Dependencies

This checkbox appears only when the Preserve coherence among pulses checkbox is unchecked.
