PMCW Radar Robust to Power Amplifier non-Linearity and IQ Imbalance with Pi/K-BPSK Modulation

European Radar Conference, 2022
This paper proposes a solution, called π/K - BPSK, to improve the robustness of BPSK-PMCW radars to front-end non-idealities. We show that some specific values of K can significantly improve the robustness to power amplifier non-linearity.

A 272-GHz CMOS Analog BPSK/QPSK Demodulator for IEEE 802.15.3d

European Solid-State Circuits Conference, 2021
A 272-GHz CMOS receiver (RX) for IEEE 802.15.3d, capable of an analog BPSK/QPSK demodulation based on a Costas loop, is presented. A QPSK demodulation is realized with the non-linear operation of a phase detector at the BPSK-demodulation Costas loop.

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 ...

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.

Confidence Evaluation of BPSK Signal Analysis Based on EVT

IEEE Transactions on Aerospace and Electronic Systems, 2020
Confidence evaluation algorithms for the analysis of binary phase-shift keying (BPSK) signals are discussed. The phase of the product of the observed signal and constructed reference signal is extracted, and its spectrum is utilized to verify confidence.

Coherent optical BPSK detection

IEEE Proceedings of the SOUTHEASTCON '91, 2002
Summary form only given. A coherent phase-locked synchronous oscillator (CPSO) was created by adding a feedforward and a feedback loop to the SO. An optically excited CPSO network was formed using a 4.3-GHz AVANTEK oscillator. Before the CPSO loop was formed, the oscillator was tuned near the subcarrier frequency with the DC bias in the loop filter ...

CORDIC based BPSK modulator

2014 International Conference on Computer and Communication Technology (ICCCT), 2014
This paper presents a novel approach for implementing Binary Phase Shift keying (BPSK) modulator and demodulator using Coordinate Rotation Digital Computer (CORDIC). The CORDIC is used in rotation mode for modulator and in vector mode for the demodulator.

A 0.9 pJ/b, Reference Clock Free, Delay-Based, All-Digital Coherent BPSK Demodulator

IEEE Solid-State Circuits Letters, 2020
This letter proposes a novel reference clock free, delay-based coherent binary phase-shift keying (BPSK) demodulator suitable for biomedical devices which receive power and data through the same wireless link. The proposed BPSK demodulator mixes the BPSK

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 ...
