OFDM Demodulator

DRS-1228

Pardis DRS-1228 is a low cost and high performance IF demodulator mainly used to replace the Baseband and modulator sections of portable analog radio links. Using a powerful modem and Baseband processor, this demodulator could retrieve the transmitting data after passing through a high multi-path channel with dispersive fading. The modulator monitors SNR, constellation, code rate, offset frequencies and other parameters on its local interface and through Ethernet interface from where user configurations could also be applied to the demodulator. Different coding rated and good frequency domain equalization along with automatic signal parameters detection make the demodulator the best choice to upgrade analog portable radio links to digital. This unit is best matched with Pardis DRS-1218 or any professional DVB-T transmitter.
