Using the Real-Time PN sequence
The generation of PN sequences in real-time on a DSK could be used in many ways. For
example, the DSK could provide the source signal for measuring the acoustic frequency re-
sponse of a room (the first step in acoustic equalization of a room, sometimes called “digital
room correction”). Or your interests may run more toward communications applications, in
which case you may want to refer to digital communications books, such as [60–65] for some
ideas. For example, the DSK could provide the spreading (and/or despreading) signal to an-
other DSK acting as a BPSK or QPSK modulator ...
