Dechirp Mixer

Dechirping operation on input signal

• 

Libraries:
Phased Array System Toolbox / Detection

Description

The Dechirp block mixes the incoming signal from the X port with a reference signal incoming through the RefX port. The signals can be complex baseband signals. The input signal can be a matrix where each column is an independent channel. The reference signal is a vector. The reference signal is complex-conjugated and then multiplied with each signal column to compute the output.

Ports

Input

RefX — Reference signal

complex-valued M-by-1 vector

Reference signal, specified as a complex-valued M-by-1 vector.

Data Types: single | double
Complex Number Support: Yes

X — Input signal

complex-valued M-by-N matrix

Input signal, specified as a complex-valued M-by-N matrix. Each column of X is an independent signal and is individually mixed with the signal input to the RefX port.

Data Types: single | double
Complex Number Support: Yes

Output

Port_1 — Dechirped output signal

M-by-N matrix

Dechirped signal, returned as an M-by-N matrix. Each column of the Port_1 port is the mixed output for the corresponding column of X.

Data Types: single | double
Complex Number Support: Yes

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using Simulink® Coder™.

Usage notes and limitations:

Does not support variable-size inputs.
