Description

Originally designed for US Navy, DSP8080-AIMM (Altitude Interference Mitigation Module) is a complete narrow band digital beam former system that takes advantage of altitude variations by removing co-channel (same frequency) interference. It is used to suppress and weed out unwanted channels broadcast from multiple locations on the same frequency as the one being used. This communication system is used to overcome hostile and unwanted interferences.

The system consists of two distinct components, namely the Tuner from WinRadio (not included in the package) and the digital beam forming part made up of multi-DSP/FPGA hardware and all the necessary host interface, IP cores and DSP codes from Sundance DSP Inc. DSP8080-AIMM is versatile enough to work with many brands of radio tuners but the first version was tested with WinRadio WR526 coherent tuner. Sundance DSP can provide a complete solution including the Tuner or just the digital beam forming system which comes in a 19inch rack system as shown in the image.

Host Interface: USB 2.0 (Gigabit Ethernet also available) Form factor: Standard 19inch rack mounted platform contains a complete multichannel phase-coherent system

Power consumption: (total) 77W
