20 Dec 1999TL;DR: In this paper, improved filter banks are created by generating a filter bank having an analysis portion and synthesis portion and obtaining wavelet coefficients (302) for each portion, which are expressed in a format capable of canonical signed digit (CSD) representation, such as integers.
Abstract: A digital data system (100) provides 1-D, 2-D and 3-D capability and multi-band channel capability. Improved filter banks are created by generating a filter bank having an analysis portion and synthesis portion and obtaining wavelet coefficients (302) for each portion. The wavelet coefficients are expressed in a format capable of canonical signed digit (CSD) representation, such as integers (304). The canonical signed digit (CSD) representation is controlled by a value, N, selected to control resolution of the CSD coding. Optimized CSD-coded wavelet coefficients are used as filters for data signals (316).

24 Apr 2005TL;DR: In this paper, a method of controlling location information of subscribers (210, 212, 222) in a wireless, ad-hoc communications network (200) was proposed, where at least portion of said nodes are provided with Home Location Registers (HLRs) (206, 218, 228) and each of the nodes (204, 216, 226) has a Visitor Location Register (VLR) (208, 220, 230).
Abstract: A method of controlling location information of subscribers (210, 212, 222) in a wireless, ad-hoc communications network (200). The network (200) comprises a plurality of nodes (204, 216, 226), wherein at least portion of said nodes are provided with Home Location Registers (HLRs) (206, 218, 228) and each of said nodes (204, 216, 226) has a Visitor Location Register (VLR) (208, 220, 230). When an operation of a first node (216) is to be reconfigured at least a part of records from a first HLR (218) assigned to said first node (216) are transferred to at least one of the other nodes (226) of the network (200).

30 Jun 2004TL;DR: In this article, the authors proposed a method for equalizing a speech signal generated within a pressurized air delivery system, the method including the steps of: generating an inhalation noise model (1152) based on inhalation noises; receiving an input signal (802) that includes a speaker signal; and equalizing the speech signal (1156) using the noise model.

TL;DR: A novel multicast clustering scheme based on a grouping genetic algorithm is proposed to maximise the aggregate data rate and can achieve near-optimal performance while outperforming the conventional unicast and multicast schemes.
Abstract: The spectral inefficiency problem faced by the conventional multicast schemes in OFDMA-based multicast systems is investigated. To improve spectral efficiency, the multicast problem is formulated as a combinatorial clustering optimisation problem where multicast groups are divided into smaller subgroups and subcarriers are allocated to each subgroup. A novel multicast clustering scheme based on a grouping genetic algorithm is proposed to maximise the aggregate data rate. Simulation results show that the proposed scheme can achieve near-optimal performance while outperforming the conventional unicast and multicast schemes.

21 Aug 2009TL;DR: In this paper, a switch (236) under the control of a data line (202) is placed in parallel with the series coupled power limiting resistor (232) and overcurrent protection device (234), which limits the maximum battery system current.
Abstract: A battery pack (200) includes a power limiting apparatus (230) comprising a power limiting resistor (232) in series with an overcurrent protection device (234). A switch (236) under the control of a data line (202) is placed in parallel with the series coupled power limiting resistor (232) and overcurrent protection device (234). When the switch (236) is enabled via the data line (202), current limiting is provided via the switch and a fuse. When the switch (236) is disabled via the data line (202) current limiting is provided via the overcurrent protection device (234) which limits the maximum battery system current.
