Physical Channel and Signal Subcomponents

Scrambling, symbol modulation, layer mapping, precoding, resource mapping

Use low-level physical channel and signal subcomponent processing functions to:

  • Perform uplink scrambling and descrambling.

  • Generate pseudorandom binary sequences.

  • Perform symbol modulation and demodulation.

  • Perform precoding and deprecoding.

  • Perform transmit diversity decoding.

  • Generate root Zadoff-Chu complex number sequences.
