Constructing Multichannel Frame-Based Signals

A frame-based signal with N channels and frame size M is represented by a sequence of M-by-N matrices. (The special case of N = 1 represents a single-channel signal.) There are two basic ways to construct a multichannel frame-based signal from existing signals:

• By horizontally concatenating existing frame-based signals -- Multiple individual frame-based signals (with the same frame rate and size) can be combined into a multichannel frame-based signal using the Simulink Matrix Concatenation block. Individual signals can be added to an existing multichannel signal in the same way.

  

• By buffering existing sample-based or frame-based signals -- Multichannel sample-based and frame-based signals can be buffered into multichannel frame-based signals using the Buffer block in the Buffers library (in Signal Management).

  

The following sections explain the two methods of constructing multichannel frame-based signals:

• Concatenating Independent Frame-Based Signals into Multichannel Signals
• Buffering Sample-Based and Frame-Based Signals
