    Abstract: An apparatus and method for estimation of signal-to-noise ratio (SNR) with low bias that is effective for both positive SNRs and small to negative SNRs. The estimation is based on an iterative solution for the maximum likelihood estimate of the amplitude from which the SNR can be computed. The estimation is applicable for various modulated systems, including BPSK, QPSK and MPSK.

    Abstract: A method and apparatus for estimating and reporting the quality of a wireless communication channel between a wireless transmit/receive unit (WTRU) and a Node-B. A modulated signal is received from the Node-B over the communication channel and a channel estimation is performed on the modulated signal to provide a channel estimate. In one embodiment, the modulated signal is demodulated based on the channel estimate to provide a demodulated signal and a signal-to-interference (SIR) estimate based on the demodulated signal is obtained. The quality of the communication channel is estimated based on at least the SIR estimate. In an alternate embodiment, a SIR estimate based on the channel estimate is obtained. The quality of the communication channel is estimated based on the SIR estimate and additional information including at least one of delay spread, transmit power and WTRU velocity information.

    Abstract: The present invention is related to a method and apparatus for estimating signal-to-noise ratio (SNR) based on dedicated physical channel (DPCH) pilot symbols in a wireless communication system. A receiver receives a DPCH transmission and a despreader despreads the received DPCH transmission. A selector selects pilot symbols in the despread DPCH transmission. A signal power estimator estimates signal power based on the pilot symbols, and a noise power estimator estimates noise power based on the received DPCH transmission. A SNR estimator estimates an SNR based on the signal power estimation and the noise power estimation. The noise power estimator may calculate the noise power estimation either based only on pilot symbols or based on both pilot symbols and non-pilot symbols. The DPCH transmission may be transmitted using more than one antenna for transmit diversity.

    Abstract: A receiver which suppresses inter-cluster multipath interference by processing an impulse channel response consisting of two multipath clusters, each cluster having groups of signals with multiple delays. In one embodiment, the receiver includes a single antenna and parallel-connected delay units used to align the groups of signals before being input into respective sliding window equalizers. The outputs of the equalizers are combined at chip level via a combiner which provides a single output. In another embodiment, a cluster multipath interference suppression (CMIS) circuit is incorporated into the receiver. The CMIS circuit includes a hard decision unit and a plurality of signal regeneration units to generate replicas of the multipath clusters. The replicas are subtracted from the respective outputs of the delay units and the results are input to the respective sliding window equalizers. In another embodiment, multiple antennas are used to receive and process the clusters.

    Abstract: A SOVA decoding method determines, for each information symbol time and each state of a decoding trellis, a vector of probabilities for each possible symbol value in accordance with transition path probabilities for reaching the state with respective information symbol values and probability vectors for the states at the previous information symbol time from which the state can be reached, and also determines a total probability for each state. A soft output is provided by summing probabilities for corresponding symbol values all states of the trellis at an information symbol time relating to the start of the vectors, corresponding to a desired survivor path length. The vectors can comprise probability ratios instead of probabilities to reduce storage especially for binary signal decoding, and logarithmic probabilities or ratios can be used to simplify computation.

    Abstract: The present invention relates to a device for preparing assay samples using a number of microscope slides. Each slide has a number of assay reaction surface locations spaced on the planar surface of the slide. In preferred embodiments, the device comprises, in part, a microscope slide holder that has the exterior dimensions of a SBS standard microplate, such as a 96 well plate. The device accepts conventional microscope slides equipped with sixteen microarray surfaces spaced nine millimeters apart on center, or four for a 96 well plate. Individual chamber plates are placed on top of the slides, creating an individual well above each assay reaction surface location. In preferred embodiments, each assay reaction surface location can comprise a microarray of multiple reactive sites. Thus, parallel processing can be done of samples for genomic or proteomic profiling. An advantage of the present invention is that one can use the conventional high throughput assaying equipment for SBS standard microplates while using conventional microscope slides, thereby allowing the use of robotic assay reading equipment designed for slides.
