    Abstract: Data estimation is performed in a wireless communication system using both oversampling and multiple reception antennas. A receive vector is produced for each antenna at a sampling interval which is a multiple of the chip rate of the received signal. A channel response matrix is produced for each antenna at a preferred multiple of the sampling rate. Each receive vector is processed using a sliding window based approach, where a plurality of successive windows are processed. For each window, a combined circulant channel response matrix is produced using the channel response matrices. Using the combined circulant channel response matrix and a combined received vector comprising each received vector in a discrete Fourier transform based approach to estimate a data vector corresponding to that window; and combining the data vector estimated in each window to form a combined data vector.

    Abstract: A heat-dissipating fin assembly (1) includes a plurality of individual fin plates (12) arranged side by side. Each fin plate includes a main body (14). First and second flanges (16, 18) extend perpendicularly from opposite edges of the main body of each fin plate. A pair of spaced first bridge-shaped tabs (20) extends perpendicularly from the first flange toward the second flange. A pair of spaced second bridge-shaped tabs (24) extends perpendicularly from the second flange toward the first flange. Projections (28) are stamped from the main body opposing to the first and second bridge-shaped tabs. The tabs of each fin plate are interlocked with the projections of an adjacent fin plate. In this manner, all the fin plates are assembled together. The heat-dissipating fin assembly is thus formed.

    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: A receiver comprises a plurality of antenna elements for receiving a data signal. Each antenna element has a plurality of Rake fingers. Each Rake finger processes a received multipath component of the received data signal of its antenna element by applying a complex weight gain to that received multipath component. A complex weight gain generator determines the complex weight gain for each Rake finger for each antenna element using an input from all the Rake fingers. A summer combines an output of each Rake finger to produce an estimate of the data signal.

    Abstract: A process for implementing a market neutral relative value strategy to provide up-to-the-minute equity trading recommendations includes selecting pairtrades, each having both high correlation coefficient and high de-trended correlation coefficient. The de-trended coefficient is determined for a time interval selected such that a starting price of one of the stocks of a pairtrade is substantially equal its ending price. The process further includes calculating an optimal financial hedge ratio by determining regression slopes of the stocks in each selected pairtrade with respect to one another. The selected pairs are further compared with a plurality of templates to select only valid pairtrades whose amplitude and number of crosses through and deviations from the regression line match at least one of the templates. Applying a modified LaGrange-Urenbeck process to determine the optimal cut-loss and profit taking boundaries further optimizes each of the valid pairtrades.

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