摘要： A system and method for providing enhanced caller identification (caller ID) information to a user is described. A broadband access gateway communicatively coupled to a plurality of access devices may collect information about multimedia content available on the access devices and/or information exchanged with access devices. The gateway may search the collect information upon receiving information identifying a called or calling party, to find information that may be associated with the called or calling party. Selected items of the information associated with the called or calling party may then be delivered to the access device of the called or calling party. Information accessible to the gateway via a broadband connection may also be made available to the user of the access device.

摘要： A system and method of registering or exchanging information about the availability of multimedia information and services is disclosed. Access devices in a wireless local area network (WLAN) and/or personal area network (PAN) may register, with a wireless broadband access gateway, selected information about multimedia information and services that they have and may share. Information about the available multimedia information and services may be shared by the wireless broadband access gateway with other access devices within the coverage area of the WLAN or PAN. Access devices may then access the multimedia information and services of other access devices via the wireless broadband access gateway, based upon information identifying and authenticating the recipient. A broadband connection permits the gateway to pass multimedia information and service activity to and from the access devices within the coverage area of the WLAN or PAN.

摘要： Providing of a universal wireless headset begins for an incoming call by determining whether a piconet can be established between an initiating device and the wireless headset. If a piconet cannot be established, the processing continues by determining whether the headset can establish a piconet with a device coupled to a network. The network may be a local area network, which includes wireless devices and/or wired devices. When the wireless headset can establish the piconet with a device coupled to the network, the piconet is established. Once the piconet is established, the processing continues by establishing a logical connection between the initiating device and the device coupled to the network. As such, the incoming communication is supported via the logical connection and the piconet.

摘要： In a receiver that includes a plurality of receiving antennas that supply signals to associated OFDM receiving modules, and the receiving modules provide signals that are applied to a detector, channel parameters that are needed for proper detection are estimated during normal operation, in addition to an initial estimate based on a known training sequence. In computing the channel impulse response estimates between the signal received at that receiving antenna and the various transmitting antennas, an nK0×nK0 matrix of terms (qxy[l]) is developed. The inverse of the matrix is then computed, and the computed matrix inverse is multiplied by a vector of terms (pi[l]), to obtain a vector of nK0-sample channel impulse response estimates.

摘要： A joint data (features) and channel (bias) estimation framework for robust processing of speech received over a channel is described. A trellis encoded vector quantizer is used as a pre-processor to estimate the channel bias using blind maximum likelihood sequence estimation. Sequential constraint in the feature vector sequence of a speech signal is applied for the selection of the quantized signal constellation and for the decoding process in joint data and channel estimation. A two state trellis encoded vector quantizer is designed for signal bias removal applications.

摘要： The recovery of each signal in a transmitted signal including a pair of superimposed signals is improved by the use of linear prediction. The pair of signals includes various combinations of analog and digital signals, e.g., an analog signal sample superimposed upon a digital signal sample, or a digital signal sample superimposed upon another digital signal sample. In a first embodiment, prediction coefficients for the analog signal are generated from the received signal. These coefficients are then used to recover the analog and digital signals from the received signal. In a second embodiment, the analog signal recovered, pursuant to the first embodiment, is considered a tentative estimate of the analog signal, and prediction coefficients for this tentative analog signal estimate are formed and used to generate final estimates of the analog and digital signal.

摘要： A model-based printing method and system for generating halftone output images corresponding to gray-scale-coded input signals. Models for individual two-level (e.g., black on white) printer types allow predicted printer error signals to be generated which can be used to modify the gray-scale coded signals in such manner as to produce binary signals which, when applied to the printer, create halftone images of enhanced quality. In an alternative embodiment binary signals are selected which minimize an error function based on the difference between (i) a predicted perceived image corresponding to the gray scale inputs as filtered by an eye-model filter and (ii) the halftone image resulting from filtering of the binary sequence by a filter modeling the printer followed by the eye-model filter.

摘要： A method for a post-processors provides reliability information about every decoded data symbol at the output of an arbitrary decoder. This reliability information is generated by comparing the decoded sequence to a small list of alternative sequences which differ from the decoded sequence at least in the symbol for which the reliability is being evaluated. It is shown that this algorithm is a simplification of the optimal symbol-by-symbol detector (OSSD).
