Multicarrier systems and filter banks

Performance analysis of multicarrier modulation systems using cosine modulated filter banks

In this paper we compare the performance of biorthogonal cosinemodulated transmultiplexer filter banks with today’s multicarrier modulation systems whose transceivers are based on DFT. In contrast to early works on transmultiplexer filter banks that concentrated on the derivation of perfect reconstruction constraints of the filter bank or prototype design, this study takes into consideration a ...

An Efficient Filter Banks Based Multicarrier System in Cognitive Radio Networks

In cognitive radio techniques, OFDM is usually regarded as the physical layer candidate. However, the weaknesses of the OFDM technique, i.e., using plain FFT for spectral analysis , decreased bandwidth efficiency due to CP (cyclic prefix), high out-of-band emission, have been pointed out and the introduction of filter banks based multicarrier (FBMC) system has been advocated by a number of auth...

Design of M-band complex-valued filter banks for multicarrier transmission over multipath wireless channels

The orthogonal M-hand complex-valued filter banks have more flexibility in terms of frequency response. In this paper, a new general design method for orthogonal Mband complex-valued filter hanks is presented for multicarrier (MC) transmission to reduce intersymbol and interchannel interference (IS1 and ICI). The design includes three procedures. First, a parameterization method is used to desi...

Wavelets And Filter Banks

Wavelet and short-time Fourier analysis is introduced in the context of frequency decompo-sitions. Wavelet type frequency decompositions are associated with lter banks, and using thisfact, lter bank theory is used to construct multiplicity M wavelet frames and tight frames. Theway in which lter banks lead to decomposition and recomposition of arbitrary separable Hilbertspaces is...
