In this paper, we extend the partial modulation technique to obtain the highly desired linear-phase (LP) characteristics of oversampled nonuniform filter banks (NUFBs), which makes it possible to design LP oversampled NUFBs based on the efficient modulation technique. Further for the subbands with sampling factors violating the guard band constraint, a phase modification structure is also proposed...
The combination of adaptive beamforming (ABF) with space-time block coding (STBC) has been widely studied in wireless communications. However, all of the existing schemes ignore the effect of mutual coupling (MC) between array elements. In this paper, an adaptive space-time transmit scheme is firstly introduced using the maximization of the output mean SNR and the minimization of the symbol error...
The majority of the existing work on designing nonuniform filter banks (NUFBs) cannot achieve linear-phase (LP) property, because of the high complexity associated with phase distribution. This correspondence proposes an idea of partial cosine modulation to obtain the LP property of NUFBs with rational sampling factors. It makes the efficient modulation technique possible to be used to design LP NUFBs...
This paper mainly presents some recent advances in designing nonuniform filter banks (NUFBs), including direct and indirect methods, along with the detailed review on the typical design methods. Starting with the description of the motivations behind using NUFBs in real applications, we identify some problems existing in the current work. As a new contribution, we then propose a simple design method...
