APPLICATION OF MISMATCHED FILTER THEORY TO BANDPASS IMPULSE-RESPONSE MEASUREMENTS

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