Automatic identification of the digital modulation type of asignal has found applications in many areas, including software defined radio (SDR), surveillance and threat analysis. This paper describes the FPGA based implementation of Automatic Modulation Recognition (AMR) algorithm foradvanced communication payload. A wavelet transform based algorithm which(More)
In this paper, the design and FPGA implementation of a Digital QPSK Demodulator which supports variable data rates varying from 4.88Kbps to 2Mbps and higher is described. The paper presents the design of carrier and symbol recovery loops in details. The design is made platform independent so that it can be ported to any FPGA device. Proposed design is(More)
Today, the primary constrain in wireless communication system is limited bandwidth and power. Wireless systems involved in transmission of speech envisage that efficient and effective methods be developed (bandwidth usage & power) to transmit and receive the same while maintaining quality-of-speech, especially at the receiving end. Speech coding is a(More)
