Sample-Based Multichannel Signals

Sample-based multichannel signals are represented as matrices. An M-by-N sample-based matrix represents M*N independent channels, each containing a single value. In other words, each matrix element represents one sample from a distinct channel.

As an example, consider the 24-channel (6-by-4) sample-based signal in the figure below, where u^t=0 is the first matrix in the series, u^t=1 is the second, u^t=2 is the third, and so on.

Then the signal in channel 1 is composed of the following sequence:

Similarly, channel 9 (counting down the columns) contains the following sequence:
