Abstract

In this paper, we discuss the application of time-varying filter in intensive spectrum resource allocation, which is constructed basing energy distribution of the pulse shaping signal. First, we analyze the system model and discuss the existence of interference when in its practical application. Then, we contrast the application of time-varying filter and traditional time-invariant bandpass filter with fixed width, concluding the benefits of time-varying filter in interference rejection. And considering the interference caused by practical channel with multipath delay and Doppler frequency shift, we proposed joint filter combined channel equalizer filter with time-varying filter, to improve spectrum efficiency and suppress interference in 2-D (t, f) plane effectively.
