Frame-Based Multichannel Signals

Frame-based multichannel signals are also represented as matrices. An M-by-N frame-based matrix represents M consecutive samples from each of N independent channels. In other words, each matrix row represents one sample (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:
