CMX8341 - Digital PMR (dPMR) Baseband Processor

General Description

The 8341FI-1.x Function Image™ (FI) implements a half-duplex digital PMR processor including: 4FSK modem, a large proportion of the dPMR™ Air Interface; Physical, Data Link and Control layers, and an embedded low bit rate RALCWI Vocoder (with no license or royalties required).

Key Features

  • Digital PMR (dPMR) Baseband Processor o dPMR (ETSI TS 102 490) Compliant o Air Interface Physical Layer (Layer 1) o Air Interface Data Link layer (Layer 2) o 4FSK Modem.
  • Soft-decision Decoding.
  • AFSD (Automatic Frame Sync Detection).
  • RALCWI Vocoder o Fully Embedded Implementation o No Licensing or Royalty payments o 3600bps Over Air Data Rate (2400bps Voice plus 1200bps Robust FEC) o 4-bit Viterbi Soft-decision Decoding.
  • Analogue PMR (Legacy mode) o Full Audio Band Proc.
