  • Publication number: 20050257112
    Abstract: A novel technique for combining deinterleaving operation with post FFT modules in a receiver to reduce processing time. In one example embodiment, the deinterleaving operation, in the post FFT module, is combined with FFT and demapper operations to reduce the processing time and complexity.

  • Publication number: 20050195770
    Abstract: A system for receiving and handling a scrambled input data signal that includes a preamble with a start of frame delimiter (SFD) initiates an SFD search on the scrambled input data, thereby attempting to save an initialization period. The initialization period may be of the order of 7 ?S, and its saving results in improved timeline management enabling antenna diversity and the possible use of high performance algorithms. The system may use two parallel paths for signal processing, each having an SFD detector and a descrambler. If the detected SFD is short, then the second path is disabled, and if it is long, then the first parallel path is disabled. Alternatively, the first path can be used for a finite period of time (for e.g., 40 symbols) and if the SFD is still not detected, the first path is disabled, and the system uses only the second path.

  • Publication number: 20050159120
    Abstract: A technique for signal distortion compensation using a filter that can support a higher delay spread distortion without substantially increasing hardware complexity. In one example embodiment, an adaptive receiver design compensates for signal distortions with the use of non-uniform tap delay filters. The non-uniform tap delay filters are used to output an adaptively channel matched signal for decoding.

  • Publication number: 20030208408
    Abstract: A method, system and computer program product for conducting an online auction of a plurality of heterogeneous items between a plurality of selling and potential purchasing parties. The method includes the the steps of accepting an offer in respect of an item, accepting one or more subsequent offers that is/are preferable to a previously accepted offer, and rejecting the previously accepted offer. While the offer/s is/are binding on a party making the offer, acceptance of the offer/s is/are not binding on a party accepting the offer. Classes of “seller strategies”, for offering items to potential purchasing parties, and “buyer strategies”, to decide which offers to accept, are also disclosed. As a result of the interaction of the buyer and seller strategies, the auction mechanism converges to an allocation of items to buyers at particular prices and assists in discovering a free and fair competitive equilibrium price.

  • Patent number: 6571216
    Abstract: A methodology and system allows a plurality of reward scheme owners to give differential rewards, through a plurality of reward distribution agents, to various users based on the user profile. The reward scheme owner may be a seller, a manufacturer, a sales promotion agent or even an intermediary. Similarly, the reward distribution agent may be an on-line or a physical retailer, a broker, a seller or an intermediary. Also the users may be consumers, businesses, brokers or other intermediaries. In one specific case, a reward scheme owner defines a plurality of reward schemes, including at least one differential reward scheme giving different rewards to different users. The reward scheme owner communicates these to a central reward scheme database server. The reward scheme owners may or may not advertise these schemes. The user visits an online or a physical store.

  • Publication number: 20020147636
    Abstract: An electronic coupon, an electronic commerce system, and a method for the honoring of electronic coupons utilizing computing equipment are disclosed. In the method, an issuing party issues an electronic coupon to a customer. The customer presents the coupon for redemption to a redemption party. The redemption party transmits the coupon to an authentication party for authentication. If authentic, the authentication party charges the redemption party a fee and passes that fee to the issuing party. The redemption party honors the coupon for the customer and seeking reimbursement of the fee from the issuing party. The electronic coupon has a plurality of data fields, including: a coupon identifier, x, a first one-way hash function field, f(x), and a secure signature field.
