Physical Channel and Signal Subcomponents

PRBS and low-PAPR sequence generation, symbol modulation, layer mapping, and transform precoding in 5G NR

Use 5G Toolbox™ low-level physical channel and physical signal subcomponent functions to:

  • Generate pseudorandom binary sequences for scrambling.

  • Generate low peak-to-average power ratio (low-PAPR) sequence.

  • Perform symbol modulation and demodulation.

  • Perform layer mapping and demapping.

  • Perform transform precoding and deprecoding.
