Mobile Phase Recovering Equalizer FPGA core
The Mobile Phase Recovering Equalizer (MPRE) FPGA core combines Channel Equalization, Phase Recovery, and Symbol Slicing in a single module. The Mobile Phase Recovering Equalizer is ideal for medium-to-high data rate applications where range, power efficiency, and reliability in mobile channels are desired. Advanced, patent pending, signal processing in the MPRE provides robust and reliable QPSK demodulation in high Doppler and mobile multipath environments. Mobile multipath radio environments that are too harsh for broadband single-carrier QPSK reception can be used reliably with the MPRE.
The Mobile Phase Recovering Equalizer fits easily into the signal flow of most single-carrier demodulators with a minimal amount of configuration and supporting input signals.
