Performance analysis of wavelet-based generalized sidelobe cancellers

In this paper, we carry out a performance analysis of the recently addressed wavelet-based generalized side-lobe canceller (GSC) which employs a set of regular M-band wavelet filters in the design of the blocking matrix involved. We begin our analysis by developing a closed form expression for the output signal-to-interference-plus-noise-ratio (SINR) of the GSC with a linear constraint under one jammer environment. Then, basing on this expression, we examine the relationship between the choices of the parameters involved in the wavelet-based GSC and the corresponding output SINR. Some simulations are provided to justify these results.
