Physical Layer Subcomponents

Downlink and uplink subcomponents for transport channels, physical channels, and physical signals

Use LTE Toolbox™ low-level downlink and uplink physical layer functions to explore transport channel, physical channel, and physical signal subcomponent processing.

Transport Channel Subcomponents
CRC, code block segmentation, convolutional and turbo coding, rate matching and recovery, TBS lookup, MIB coding, MCS lookup
Physical Channel and Signal Subcomponents
Scrambling, symbol modulation, layer mapping, precoding, resource mapping

Featured Examples

LTE DL-SCH and PDSCH Processing Chain

In LTE the Downlink Shared Channel (DL-SCH) is a transport channel used for the transmission of user data, dedicated control and user-specific higher layer information and downlink system information. The Physical Downlink Shared Channel (PDSCH) is the physical channel that carries the DL-SCH coded data. This example shows the different stages involved in the Downlink Shared Channel (DL-SCH) and Physical Downlink Shared Channel (PDSCH) processing and provides access to the data from these intermediate stages.
