Instantaneous MISO Separation of BPSK Sources
2006We 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.

On suboptimum receivers for DS–CDMA with BPSK modulation
Signal Processing, 2005In 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.

Confidence Test for Blind Analysis of BPSK Signals
IEEE Transactions on Aerospace and Electronic Systems, 2019A 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 ...

Punctured turbo-codes for BPSK/QPSK channels
IEEE Transactions on Communications, 1999Summary: 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 turbo coded BPSK for an aeronautical channel
2013 47th Annual Conference on Information Sciences and Systems (CISS), 2013In this paper, we present the results of using a turbo decoder to retrieve a serially encoded data stream, which has been transmitted over a multipath channel. The transmitted data streams are Binary Phase Shift Keying (BPSK) modulated signals, which are encoded using two rate one-half (1/2) recursive systematic convolutional (RSC) encoders, and then ...

Performance of BPSK and GMSK with multiple cochannel interferers
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002The 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

Non coherent demodulation of BPSK secure symbols.
2013From the communication channel and implementation aspects of communications, the transmission environment may be sufficiently degraded that introduces practical difficulties in acquiring and tracking a coherent demodulation reference signal. Coherent receivers require exact knowledge of the channel phase for optimum performance.
