Downlink Channels

Downlink physical signals, physical channels, transport channels, control information, and OFDM modulation

Use LTE Toolbox™ mid-level downlink channel processing functions to:

  • Create physical signals and physical channels for transmission and reception.

  • Create, encode, and decode transport channels.

  • Create, manipulate, encode, and decode control information messages.

  • Perform OFDM modulation and demodulation.

For function mapping within the downlink grid, see Downlink Physical Channels Grid and Downlink Physical Signals Grid.


  • Physical Signals
    Synchronization signals (PSS and SSS), downlink reference signals (CRS, DM-RS, CSI-RS, and PRS)
  • Physical Channels
    PBCH, PDSCH, PDCCH, PCFICH, PHICH and EPDCCH coding, modulation, indices, scrambling sequence
  • Transport Channels
    BCH coding, DL-SCH coding and information
  • Control Information
    DCI creation, manipulation, coding, and information; CFI coding; UL-PMI information and selection
  • OFDM Modulation
    Orthogonal frequency division multiplexing modulator, demodulator, dimension information
