Description

The STA400A is a satellite transmission system based on two geostationary satellites on the East and West coasts of the Continental United States (CONUS). In the urban areas, where the line of sight reception of the satellites is difficult or not possible, the service is covered by terrestrial repeaters adopting a MultiCarrier Modulation scheme.

Designed for digital radio receivers compatible with the XMRadio SDARS System, the STA400A Channel Decoder integrates all the functions to demodu- late and decode the incoming satellite and terrestrial signals after the RF Front-End down-convertions: Analogto- Digital conversions, satellite and terrestrial demodulations, AGCs, frame synchronization and demultiplexing, Viterbi decoding, time and spatial diversity combining, Reed-Solomon decoding and deinterleaving, Prime Rate Channel (PRC) demultiplexing, Payload Channel (PC) selection.

At the end of the demodulation and decoding processes a configurable serial data stream is made available to STA400A, the Service/Source Decoder, via the PC BitStream interface.
