Single-Rate Processing with OQPSK Demodulator Block

This example shows the OQPSK Demodulator Baseband block configured for single-rate processing using integer or bit for the input type.

Open the slex_oqpskdemod_framebased model.

model = 'slex_oqpskdemod_framebased';
open_system(model);

In single-rate processing mode, the input and output signals have the same port sample time. The block implicitly implements the rate change by making a size change at the output when compared to the input. In this mode, the input column vector length must be an integer multiple of the Samples per symbol parameter.

sim(model);
  • When you set the Output type parameter to Integer, the output width is the number of input symbols.
  • When you set Output type parameter to Bit, the output width is two times the number of input symbols.
