This paper proposes a crosscorrelation phase shift scheme to improve the performance of linear joint detection. For the calculation of crossorrelation matrix with original outputs of matched filters brings loss due to inter symbol interference(ISI) in linear multiuser detection, the scheme considers ISI as linear combination of multipath delay and spreading code, and proposes a crossorrelation matrix...
This paper presents the bit error probability (BEP) of impulse radio communication systems with Gaussian monocycle as the impulse. Results show that the BEP of asynchronous polarization randomized time-hopping (TH) impulse radio communication systems has no obvious relationship with the order of Gaussian monocycle, but has certain relationship with the width of Gaussian monocycle. The narrower the...
This paper analyzes the performance of IR-UWB (impulse radio ultra wide-band) with different monocycles in the presence of interference generated by the UMTS/WCDMA systems. The bit error rate is derived for the IR-UWB with n-order derivative Gaussian monocycle in the presence of UMTS/WCDMA interference. The relationship between the anti-UMTS interference ability of IR-UWB and the derivative order...
