The Cognitive radios are intelligent Software Defined radios which is aware of its environment by scanning and identifying spectrum holes. The knowledge of the modulation scheme of the received signal is significant to judge the channel and configure the SDR to transmit and receive. The two broad fields of modulation recognition are pattern recognition and decision theoretic approaches. This paper...
FPGAs are playing a very significant role in software defined Radios (SDR) and Cognitive radios (CR). The SDRs and CRs are capable of running different waveforms which may use different modulation techniques, source coding and channel coding. These reconfigurable radios have to load the waveforms into the FPGA based on their requirements without interrupting the system. The user has to load large...
The role of FPGAs in software defined Radios (SDR) and Cognitive radios (CR) are very significant. These radios have to load different waveform depending on their requirements which may use different source coding, channel coding and modulation schemes. The user has to load large bit files even for small changes in the waveforms. In SDRs and CRs the configuration time and current consumption plays...
