Microwave Radio Communications is showcasing in the booth, the DRS4000 dual digital diversity receiver.   The DRS4000 diversity system uses advanced maximal ratio combining (MaxRC), a technology that employs multiple receiving antennas to help combat multi-path fading.   The DRSMaxRC is perfect for outside sporting events.

“They never lose power,” says Jacqueline Roy, Microwave Radio Communications marketing communications manager.

The DRS4000 combines multiple MaxRC sites to form a cellular diversity network. In addition to supporting DVB-T COFDM, the DRS4000 also includes an LMS-T demodulator. Developed by MRC’s sister company Link Research, LMS-T combines DVB-T like OFDM techniques with powerful LDPC error correction codes to achieve a 30% improvement in throughput and a corresponding increase in robustness.

The front panel includes two display screens, one that provides real time metrics for every channel, and a second screen that displays decoded video with spectrum monitor overlay. The integrated SD/HD decoder supports both 4:2:0 and 4:2:2 profiles.    

Microwave Radio Communications also announced that the company’s Link Research HDTV wireless is still supplying NASCAR events with microwave systems.   “They have the lowest delay, “adds Roy.
