FPGA For Communications Applications

Develop advanced DSP algorithms and test in real time

Migration of digital processing toward antenna

• More digital, less analog

Multiple & smart antenna processing

Better spectrum utilization

• Higher performance filters, high density signal constellations

Advanced error control - Turbo codes and MAP decoders

Software / configurable radio

• Multiple modulation, error correction and data encryption schemes with one platform

Communications application, traditionally one of the strongest FPGA market segments, benefit from FPGA solutions. The ability to test new computationally intensive communications algorithms such as Turbo codes and MAP decoders (yields 1.5 dB better signal to noise for high data rates) in real time over a real channel helps to speed the introduction of the new standards such as CDMA2000 and WCDMA.

FPGAs move digital processing closer to the antenna enabling cellular infrastructure smart antennas. Algorithms can also independently process signals from two antennas and dynamically pick the best results.

“Software radio” now becomes “configurable radio”. FPGAs process data sample rate above 100 MHz. Satellite modems, cellular infrastructure, and military radios will be among the first to benefit from a fully programmable solutions
