Signal Concepts
3-13
(or time slice) from N distinct signal channels, and each matrix column
represents M consecutive samples from a single channel.
This is a simple structure, as illustrated below for a sample 6-by-4 frame
matrix.
Consider a sequence of frame matrices, where u
t=0
is the first matrix in a
series, u
t=1
is the second, u
t=2
is the third, and so on.
Then the signal in channel 1 is the following sequence.
Similarly, the signal in channel 3 is the following sequence.
See the following sections for information about working with frame-based
multichannel signals:
•“Creating Signals” on page 3-33
•“Constructing Signals” on page 3-42
•“Deconstructing Signals” on page 3-54
