Automatic Analog/Digital Modulation Recognition for SDR Implementation with FPAA

Automatic modulation recognition for software defined radio (SDR) is a research focused on developing 3G and 4G wireless communications with adaptive modulation capability. The existing automatic modulation recognition technology does not satisfy the seamless demodulation requirement of the SDR. The design of automatic modulation recognition method with reduced computational complexity and fast processing speed is needed. The radio systems are increasingly incorporating dynamically configurable software into software defined radio (SDR) design. The ability to change software after manufacture makes SDR a perfect platform for designing Cognitive Radio (CR). The equipment must handle higher channel densities and must meet a high-availability standard to provide uninterrupted service. In addition, the equipment will be flexible to accommodate various air protocols. The statistical performance of the fast automatic modulation recognition associated with its implementation using the SDR is discussed in this work.
