The IP Core is delivered as modifiable source code for integration into SoC or FPGA. The Combo Demodulator IP Cores contains a DVB-S2 QPSK and 8PSK, Enhanced DVB-S and DirecTV QPSK legacy, Multi-tap ...

Since no separated PBS is utilized, the demodulator has much smaller chip size compared with a conventional DP-QPSK demodulator which contains two PBSs and two 90° hybrids. Simulation with 2-D ...

OQPSK_demodulator_Start - QPSK Plugin is triggered to start from DDE Tracking Client by this command Needed for M-N2-3. send_tracking_frequency_On - Starting Doppler frequency correction for Meteor ...

Corresponding research on carrier synchronization for QPSK coherent demodulation is carried out. By comparing several carrier recovery loops, The quaternary loose tail loop is selected as carrier ...

Abstract: We propose a simple QPSK demodulation method in hierarchically modulated T-DMB with DQPSK and QPSK. For the T-DMB system based on OFDM with DQPSK modulation, the data rate can be increased ...

The completed composite demodulator with wall wart. At the end of the pipe in every FM station operating in stereo — which probably is 99.5% of the over 7,000 FM outlets operating here in the United ...

The modulation scheme, moduType must be one of 'BPSK', 'QPSK', '16QAM', '64QAM', '256QAM'. symbsIn must be a column vector. 'mothod' - Specified as 'max-log-map' or 'approx'. Demodulation is performed ...

Digital modulation is digital-to-analogue conversion (DAC) while demodulation or detection is analogue-to-digital ... quadrature phase shift keying (QPSK), and (c) eight phase shift keying (8PSK) ...

Fig. 3: Simplified block diagram of the project. The QPSK modulator and demodulator with Costas phase-locked loop and DAC/ADC drivers are placed in FPGA. Also, the GNU Radio application prepares the ...
