Error Probability Analysis of Nyquist-I Pulses in Intersymbol and Cochannel Interference

Abstract

The coexistence of different types technologies supported by the same infrastructure introduces unwanted interference that affects negatively the communication system. In this manuscript, recently proposed Nyquist-I pulses are evaluated in terms of bit error rate (BER) considering first, the effect of cochannel interference (CCI) and later, inter-symbol interference (ISI) and CCI simultaneously, under the effects of time jitter. The results indicate that considering a fixed interference power, as the number of interfering signals increases, the effect of the CCI also increases. Additionally, when the effects of CCI and ISI are considered simultaneously, both the magnitude of the main lobe and the magnitudes of the lateral side-lobes of the impulse response are preponderant in the calculation of the BER.
