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 ...

Instantaneous MISO Separation of BPSK Sources

2006
We present a new approach for signal separation from an undetermined instantaneous mixture of two BPSK (Binary Phase Shift Keying) signals in AWGN (Additive White Gaussian Noise) channel. The method uses frequency diversity of the mixture (frequency shift between carriers) and the fact that signals of interest are binary variables.

Delay-Based BPSK for Pulsed-UWB Communication

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
This paper proposes a practical and effective modulation technique applicable to pulsed-UWB systems that mimics the desirable, continuous spectrum of a BPSK signal without requiring an inversion in the signal path. This technique can be used for scrambling the spectrum of a PPM signal, or as a replacement for BPSK signaling.

Combination scheme of CPWPM and BPSK for digital communication

2012 Fourth International Conference on Communications and Electronics (ICCE), 2012
In this paper, we investigate a combination scheme of chaotic pulse width-position modulation (CPWPM) and binary phase-shift keying (BPSK) modulation for digital communication. There, binary information is firstly modulated onto chaotically-varied intervals of position and width of pulses by CPWPM.

Confidence Test for Blind Analysis of BPSK Signals

IEEE Transactions on Aerospace and Electronic Systems, 2019
A binary-hypothesis-test-based algorithm is proposed to assess the confidence of blind analysis results of binary phase-shift keying signals. The reference signal is first constructed based on the given analysis result. The spectrum of multiplication between observed signals and reference signals is used as a distinguishing statistic, and the decision ...

On suboptimum receivers for DS–CDMA with BPSK modulation

Signal Processing, 2005
In this paper, we will show that for direct-sequence code-division multiple access (DS-CDMA) with binary phase-shift keying (BPSK) modulation transmitted over complex baseband channels the real part of the matched-filter (MF) output and not the MF output itself should be used as sufficient statistics for further processing.

Punctured turbo-codes for BPSK/QPSK channels

IEEE Transactions on Communications, 1999
Summary: We discuss a procedure for designing high-rate turbo-codes via puncturing, with applications to BPSK/QPSK channels. Rates in the form \(k/(k+1)\), \(2\leq k\leq 16\), are considered for constituent encoders with memory sizes \(m=3\) and 4. The algorithm includes the selection of constituent encoder generator polynomials, puncture patterns, and

Performance of BPSK and GMSK with multiple cochannel interferers

Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002
The bit error rate performance of binary PSK (BPSK) and Gaussian minimum shift keying (GMSK) in the presence of multiple cochannel interferers and additive white Gaussian noise (AWGN) is analysed. In particular, a closed form expression is given to evaluate the bit error probability of BPSK with multiple cochannel interference, whereas GMSK is analyzed
