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.
