Title: Method and apparatus for improved inverse transform calculation
Inventor: MILLER SMITH RICHARD
IPC: G06F17/14
Filed: 2004-09-29
Abstract: A method is provided for determining, from DCT coded data used in MPEG video coding, the number of bits required to represent an output value which would be obtained after an inverse transform is performed on said transform coded data. The method comprises obtaining a sum of coefficient values within said transform coded data (204) and comparing this sum to a predetermined threshold value (206). As a consequence of said comparison a processor decides which inverse transform implementation, out of a number of pre-determined implementations, should be performed when decoding said transform-coded data (208, 210). For example, eight bit-processing routines may be used, which are more economic than nine bit routines if the sum is less than a threshold value.

Filed: 2004-10-15
Abstract: Transmit and/or receive diversity is achieved using multiple antennas. In some embodiments, a single transmitter chain within a wireless terminal is coupled over time to a plurality of transmit antennas (312). At any given time, a controllable switching module (310) couples the single transmitter chain to one the plurality of transmit antennas. Over time, the switching module couples the output signals from the single transmitter chain to different transmit antennas. Switching decisions are based upon predetermined information, dwell information, and/or channel condition feedback information. Switching is performed on some dwell and/or channel estimation boundaries. In some OFDM embodiments, each of multiple transmitter chains is coupled respectively to a different transmit antenna. Information to be transmitted is mapped to a plurality of tones. Different subsets of tones are formed for and transmitted through different transmit chain/antenna sets simultaneously. The balance of tones allocated to the subsets for each antenna are changed as a function of predetermined information, dwell information, and/or channel condition feedback information.

Title: Preserving privacy while using authorization certificates
Inventor: CONRADO CLAUDINE V
IPC: G06F21/62
Filed: 2004-12-13
Abstract: The invention proposes a method to provide privacy for users or a user from a group of users with respect to authorizations they are granted, where such authorizations are expressed using digital authorization certificates, and with respect to domain certificates in case of groups of users. The idea is to conceal the user identity in the certificates, while the certificate itself remains in the clear. In this way, certificates can be widely and openly available, e.g. in a public network, without a random observer being able to link a user to an authorization or to identify a user within a domain. Privacy is also provided towards the certificate verifier by means of zero-knowledge protocols, which are carried out between the user and the verifier in order for the verifier to check a user's entitlement to a certificate. Privacy is further provided towards the certificate issuer as well, by means of a mechanism that allows the anonymous (buying or) issuing of certificates from the issuer.

Title: Quadrature modulation apparatus, method, program and recording medium
Inventor: KATO TAKASHI
IPC: H04L27/36
Filed: 2005-02-10
Abstract: To correct an RF signal, which has been obtained by a quadrature modulation, without performing quadrature demodulation. There are included an in-phase multiplier (14I), a quadrature multiplier (14Q), an adder (18), a power detector (56), and an error determining part (62). The in-phase multiplier (14I) outputs an in- phase conversion signal by mixing an in-phase local signal (Lo) of a predetermined local frequency with an in-phase correction user signal obtained by adding an in-phase user signal (I signal) to an in-phase correction signal of a sinusoidal voltage outputted from an in-phase correction signal output unit (32I). The quadrature multiplier (14Q) outputs a quadrature conversion signal by mixing a quadrature local signal (Lo), which is different in phase by 90 degrees from the in-phase local signal, with a quadrature correction user signal obtained by adding a quadrature user signal (Q signal) to a quadrature correction signal, which is different in phase by 90 degrees from the in-phase correction signal, from a quadrature correction signal output unit (32Q). The adder (18) adds the in-phase conversion signal to the quadrature conversion signal. The power detector (56) measures an output voltage of the adder (18). The error determining part (62) determines, based on the measurement result of the power detector (56), the error of the quadrature modulation.
