BPSK-SIM- PPM Modulation for Free Space Optical Communications

, 2014
In this paper a hybrid PPM-BPSK modulation scheme is proposed. The numerical simulation results for the bit error rate (BER) performance of the PPM-BPSK modulation scheme in the lognormal atmospheric channel for a range of turbulence variance is ...

Performance of BPSK/BPSK and OQPSK/BPSK spread spectrum communication systems in the presence of multiple-tone jammer

Proceedings. IEEE Energy and Information Technologies in the Southeast', 2003
The error probability of BPSK/BPSK (binary phase-shift keying to binary phase-shift keying) and OQPSK/BPSK (offset quadrature phase-shift keying to binary phase-shift keying) direct-sequence spread-spectrum communication systems in the presence of the multiple-tone jammer is developed using a simple analytical technique.

The error probability for the BPSK/BPSK and OQPSK/BPSK spread spectrum communication systems in the presence of single tone jammer

[1989] Proceedings. The Twenty-First Southeastern Symposium on System Theory, 2003
The error probability of BPSK/BPSK and OQPSK/BPSK direct-sequence spread-spectrum communication systems, in the presence of the single tone jammer, is developed using a simple technique. This technique clearly illustrates the same error probability for the OQPSK/BPSK and BPSK/BPSK systems.

Nonlinear Models of BPSK Costas Loop

Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014
Rigorous nonlinear analysis of the physical model of Costas loop is very difficult task, so for analysis, simplified mathematical models and numerical simulation are widely used. In the work it is shown that the use of simplified mathematical models, and the application of non rigorous methods of analysis may lead to wrong conclusions concerning the ...

Constant Envelope Bandlimited BPSK Signal

IEEE Transactions on Communications, 1980
Summary: A modified BPSK modulation technique using premodulation filtering is presented. The modified BPSK modulator achieves a smooth phase transition from 0 to \(\pi\deg\) by going through an intermediate value of \(\pi/2\deg\). The resultant PSK signal has a very low AM component, particularly suitable for data transmission through nonlinear ...

A Novel BPSK Demodulator for Biological Implants

IEEE Transactions on Circuits and Systems I: Regular Papers, 2008
A novel binary phase-shift keying (BPSK) demodulator architecture is presented. The design employs a phase frequency detector based phase-locked loop allowing for robust performance compared to prior art. Two different circuit implementations for the novel demodulator architecture are proposed.
