A frequency-domain adaptive line enhancement based on matched filter (FDAMF) is a nonlinear filtering algorithm, which greatly improves the detection performance of matched filter in an additive white Gaussian noise. Due to strong reverberation interference, the detection performance of FDAMF drops ...
The most classical detector of active sonar and radar is the matched filter (MF), which is the optimal processor under ideal conditions. Aiming at the problem of active sonar detection, we propose a frequency-domain adaptive matched filter (FDAMF) with the use of a frequency-domain adaptive ...
Frequency-domain filtered single carrier (SC)-FDMA signal has properties of reduced peak-to-average power ratio (PAPR) and increased frequency diversity gain. However, if the carrier-frequency separation is kept the same as in the case of the transmit filter roll-off factor α=0, the adjacent...
The update (21) is an exponentially weighted filter that, instead of using (12e), includes all historical rates in the average rate. Note that, when using a very large time-scale Tc, (21) is equivalent to maximization problem (14) [164, Section 6.7]. In the literature of OFDMA ...
Feature extraction in the phase domain is based on electromagnetic scattering models which describe the sensor response to scene features. This idea of processing the SAR data using a filter matched to the phase history signature of a feature was introduced by Franceschetti (1997). Here, we ...
Spatial and frequency selectivity of a matched filter array in a conference room Matched filter array (MFA) processing uses impulse responses (IRs) in its algorithm to provide high signal‐to‐noise and 3‐D spatial selectivity. The spa... DM Grove,JC French - 《Journal of the Acoustical Soc...
Matched filter circuit used for frequency-expansion communication目的是提供一种可用小规模电路,对长代码进行应付的匹配滤波器电路,其构成为设置用于乘法运算的采样保持电路,个数为长代码的一部分那么多,从可以保持与上述个数相等的PN代码的第1乘数寄存器并行f向采样保持电路输入乘数,在该PN代码之后还有要使用的PN代码...
Work in47 is based on applying numerical methods to derive frequency domain pulse spectra/filter responses, optimised for specific modulation formats so as to result in non-T-orthogonal pulses that minimize bandwidth. Instead of optimizing out-of-band power emission for single carrier systems in ...
At the receiver, a matched filter based on Laurent decomposition is utilized to make the detection symbol-spaced. As a result, the symbol-spaced iteration can be taken between the equalizer and the decoder directly without a CPM demodulator, and we derive a symbol-spaced soft interference ...
The spatial domain and frequency domain are shown to be related when certain conditions are satisfied, one of which is space-invariance. The operation of two ideal, adaptive imaging receivers (the Channel-Matched Filter and Multiplicative-Phase Receivers) is described and their imaging performance is...
