WiMAX DL waveform Basic PUSC with preamble boosting

Basic simulation of a PUSC download with variable duty cycle

This code simulates the 48 symbol DL PUSC WiMAX waveform.

This code re-maps the carriers around Fs/2 to avoid the FFTshift issue

It also allows for playing out of an arb with a different sampling rate than the base WiMAX sampling rate.

This code uses features in Toolboxes
