Abstract
Abstract: It is discussed the characteristics of baseband transmission without interference and the relative principle of cosine roll-off system, and carried out simulation design and performance analysis of cosine roll-off system with MATLAB software. The simulation results show that the waveform has a long trailing tail after the addition of interference in the cosine roll-off system, the eye pattern has a smaller opening width, and the trace lines are blurred. The larger the roll-off factor is, the wider the eye pattern opening width is, the larger the bandwidth is, and the smaller the timing error is, which can make the digital baseband signal realize transmission without inter-symbol interference under the influence of noise. It has certain guiding significance to the transmission of actual baseband signal.
