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 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.

Constant Envelope Bandlimited BPSK Signal
IEEE Transactions on Communications, 1980Summary: 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 ...

Nonlinear Models of BPSK Costas Loop
Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014Rigorous 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 ...

A Novel BPSK Demodulator for Biological Implants
IEEE Transactions on Circuits and Systems I: Regular Papers, 2008A 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.

Mapping Rearrangement for HARQ Based on BPSK
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008In this paper we consider hybrid automatic repeat request transmission based on binary phase shift keying modulation. Our objective is to improve the performance of the retransmissions, keeping at the same time the complexity and the performance of the first transmission unaltered.

Speckle-based BPSK/QPSK demodulator
Optical Fiber Communication Conference (OFC) 2019, 2019BPSK and QPSK RF signals are demodulated without carrier frequency knowledge. The demodulator employs compressive sensing recovery methods and uses speckle within a multimode fiber to perform the requisite random signal projections.

Optimum Training for MIMO BPSK Transmission
2018 IEEE 19th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2018In this paper, we derive an analytical expression for the bit error rate (BER) of binary phase shift keying (BPSK) symbols transmitted over a multiple-input multiple-output (MIMO) system under channel estimation errors. In this wireless communications system, the receiver uses the linear minimum mean squared error (LMMSE) estimator to estimate the ...
