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 ...
A frequency-domain parallel demodulation structure combining matched filter with timing synchronization is proposed by analyzing the traditional demodulation structure based on FFT. The structure can decrease the output data rate of the matched filter, thus reducing the implementa...
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...
The discrete time-frequency matched filter should replicate the continuous time-frequency matched filter, but the methods differ. To avoid aliasing, the discrete method transforms the real-valued signal to the complex-valued analytic signal. The theory for the time-frequency matched filter does not ...

Matched filter detection is the next available technique to counter low SNR [4]. This method, however, presents many challenges as well since it requires a prior knowledge about primary user (PU) signals and CR need to be equipped with carrier synchronization and timing devices, leading to ...
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 ...
