Software radio, however, requires not only powerful transceiver architectures, but also efficient digital signal processing algorithms. A method to design and implement a very efficient decimation filter for a sigma-delta converter is proposed. The main idea of this article is to free the positions of the zeros of the classical decimation sinc-filter so to attain a high selective frequency behaviour. The filtering stage is realized by a classical sinc-filter cascaded with two other filters obtained from the first one by rotating its zeros by two opposite angles. The whole cascade yields to a simple recursive structure with a frequency behaviour more selective than a sinc-filter around the noise fold frequency bands. Although the design method may be extended to a multistage implementation, the filter design proposed deals with the first filtering stage. Since the designed filter eliminates the most part of the quantization noise, the following filtering stages may be designed with relaxed specifications adopting classical filter design methods.","PeriodicalId":435867,"journal":{"name":"2001 IEEE Third Workshop on Signal Processing Advances in Wireless Communications (SPAWC'01).

In particular, scalable coding is desirable for a heterogeneous network with varied bandwidths. We propose a scalable embedded zero tree wavelet packet (scalable EZWP) audio coding system that is a scalable audio compression system using wavelet packet decomposition and embedded zero-tree coding. We focus on multilayer low-bitrate coding which delivers high perceptual quality. In the base layer, the overlapped audio segment is first transformed by the wavelet packet. Then the local significant coefficients are extracted, quantized, and coded by variable length coding. In the enhancement layer and the full band layer, the residual signal that is the difference between the original and the output of the previous layer is coded via EZW with a psychoacoustic model and arithmetic coding. The target bit rates for three layers are 16, 32, and 64 Kbit/s, respectively. The performance of the proposed coding system is only slightly inferior to MPEG-1 layer 3 at 64 Kbit/s while it provides bitrate scalability that is suitable for multimedia distribution over the Internet with heterogeneous networks.","PeriodicalId":435867,"journal":{"name":"2001 IEEE Third Workshop on Signal Processing Advances in Wireless Communications (SPAWC'01).
