Application of mismatched filter theory to bandpass impulse response measurements

The Letter shows how a mismatched filter for the compression of a bandpass arbitrary length pseudorandom bit sequence (PRBS) may be generated. A comparison is made between the standard matched filter and the mismatched filter in terms of accuracy, dynamic range, noise gain, simplicity of implementation and flexibility to shape the probing pulse, when such filters are used for the determination of wideband bandpass impulse response measurements. This study was carried out in the context of mobile radio channel sounding.
