“…Thus, the useful component is extracted and the estimate of the interference level is made by rejector filtration, which leads to the decision formed concerning either presence or absence of the input PSK signal. Such processing procedure is used in analog PSK signal detectors [7][8][9].…”

A B S T R A C TWe have developed the effective algorithm for detecting digital binary phase-shift keyed signals. T his algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides h igh interference immunity by identifying signal presence when signal-to-noise ratio is much less that its working value in the receiving path. The introduced detector has intrinsic frequency selectivity and allows us to form the estimate of the noise level to realize the adaptive determination of decision threshold. In order to get confirmation of the detector operability and performance, we suggest the expressions for false alarm and missing probabilities. In addition, we have examine, both theoretically and experimentally, the influence of the detector parameters on its characteristics.

“…In a number of radio engineering applications, it is necessary to detect the binary phase-shift keyed (PSK) radio signals [1][2][3][4][5][6]. Analog PSK signal detectors are described in literature [7][8][9]. Their disadvantages are complexity of implementation of analog frequency multipliers and high-stable narrow-band frequency filters.…”

“…In [4], [5], the 2f detector and the autocorrelation detector are presented to detect the carrier frequency of DS-SS signal, respectively. Since the two detectors are all based on correlation, signal parameters are hard to be estimated in low signal-to-noise ratio circumstance.…”

Direct sequence spread spectrum (DS-SS) are widely for secure communications. They have many interesting properties including low probability of detection or interception. Since the DS-SS signal uses a broad bandwidth, the power spectral density can below the noise level. Therefore, the signal is difficult to detect and estimate. In this paper, a new algorithm based on fourth-order cumulant is proposed to estimate the carrier frequency of balanceable DS-SS/QPSK signal in non-cooperative communication system. The algorithm does not require a prior knowledge about the signal. In particular, it can restrain the Gaussian noise extremely. The validity of the algorithm has been verified by the computer simulation even in low signal-to-noise ratio(SNR) circumstance.

“…Because of the existence of differences between the non-periodic signals and periodic signals, some methods, such as cepstrum method, can not detect the WCDMA signals. The traditional methods of detection of weak signals, such as energy method [1], double frequency method [2], and so on, can not meet the requirements of signal detection. The conventional multiplication delay detection method [3] needs to know some prior knowledge of the signal, and in the case of noncooperative communications testing its performance will deteriorate sharply.…”

Wideband code division multiple access signal is non-periodic signal, which always floods in the background noise, bringing difficulties to the signal's reconnaissance. In order to detecting this signal, the detection method based on the quadratic fourth-order moment chip of WCDMA is proposed, and the amount of calculation is reduced by using fast calculation method about fourth-order moment chip. Experimental results show that the detection performance of the method is better than that of the double frequency method, spectrum-reprocessing method. When the false alarm probability is 1%, the detection probability of presented methods reaches above 90% at SNR -21dB.
