PACTOR 4

Data throughput: Maximum 5512 bps without compression. Approx 10500 bps with PMC using text. This is reached with approx +16 dB @ 4 kHz in an AWGN channel. Under the usual channel conditions this is 1.5 – 3 times faster than PACTOR 3

Compatibility: Backward compatible to PACTOR-1/-2/-3. Automatic negotiation during link setup.

Noticeably improved performance with PACTOR 2 and PACTOR 3

ARQ protocol: Synchronized, similar to PACTOR 3, except 10 instead of 6 speed levels (“Waveforms”) and faster switching. Bandwidth is always smaller than 2400 Hz.

Channel equalization: Iterative adaptive equalizer for the coherent speed levels (5 – 10), RAKE receiver with maximum ratio combination for the splayed speed levels (2-4). Real-time multitasking operating system.
