摘要： A system and method to more efficiently compute updated Frequency Domain (FD) Minimum Mean Squared Error (MMSE) equalization weights in a multi-stage Parallel Interference Cancellation (PIC) receiver after initial interference cancellation. The updated equalization weights (which are to be used during re-equalization) can be obtained using the old equalization weights already computed for initial interference cancellation. There is no need to invert an nR by nR matrix (where nR is the number of receive antennas) at each stage of the PIC receiver during each iteration of equalization and decoding operations. Rather, the matrix to be inverted to obtain updated equalization weights may be of the dimension n×n (where “n” equals the total number of transmission layers in a transmission scheme used in the wireless network). This significantly reduces complexity of determining updated equalization weights during FD MMSE equalization, thereby saving computational resources in a digital receiver performing such equalization.

摘要： In a blind spreading factor detecting receiver, the amplitude of a desired signal term is decoupled from the spreading factor hypothesis for that signal. Furthermore, the amplitude of the desired signal and the variance of an associated impairment term are estimated, and the estimates used to form a spreading factor hypothesis. Additionally, in one or more embodiments, a suboptimal detector does not rely on estimates of the amplitude of the desired signal or variance of the impairment term. Rather, the detector relies on scaled values that are partially despread using an initial spreading factor not greater than the smallest possible spreading factor used by the signal of interest, and combined using combining weights from a Rake or G-Rake processor, wherein the scaling factor is chosen to yield a unity ratio between the signal amplitude and noise variance after scaling.

摘要： In one aspect, the present invention greatly simplifies soft modulation calculations, in part by exploiting certain properties of Gray-mapped QAM constellations used in modulating symbols of interest. In at least one embodiment, the simplified processing includes performing the soft modulation separately for the real and imaginary parts of each symbol of interest, by using the Gray mapping to decompose each of the real and imaginary parts into binary soft modulations for each bit, and then using a computationally-efficient table lookup to calculate the binary soft modulation. Here, the look-up table comprises pre-computed bit contributions to the complex soft symbol value to be formed for the symbol of interest.

摘要： A system and method to substantially prevent Denial of Service (DoS) attacks due to Random Access Channel (RACH) overload in cellular wireless networks. Once a mobile handset is identified to cause or contribute significantly to a RACH overload of the cell, the system sends a special System Information Block (SIB) message targeted to that mobile handset and instructing it to redirect its RACH signaling to a separate RACH/PRACH (Physical Random Access Channel) resource or to a small part of the current RACH/PRACH resource. This allows most or all of the regular RACH/PRACH resource from being overloaded by a single user or a group of users. The use of a separate RACH/PRACH resource such as frequency, preamble sequence, and/or radio subframe access slot to “absorb” high volume RACH signaling traffic from a small number of malicious/defective mobile handsets substantially prevents the signaling DoS attacks in the wireless network and makes it more robust to such attacks.

摘要： A wireless communication receiver improves signal impairment correlation estimation in MIMO/MISO systems by considering different transmit power allocations and different transmit antenna power distributions in its impairment correlation calculations. The receiver may be implemented in according to a variety of architectures, including, but not limited to, Successive Interference Cancellation (SIC) Generalized RAKE (G-RAKE), Joint Detection (JD) G-RAKE, and Minimum Mean Squared Error (MMSE) G-RAKE. Regardless of the particular receiver architecture adopted, the improved impairment correlations may be used to calculate improved (RAKE) signal combining weights and/or improve channel quality estimates for reporting by receivers operating in Wideband CDMA (W-CDMA) systems transmitting HSDPA channels via MIMO or MISO transmitters. A transmitter may be configured to facilitate impairment correlation determinations by wireless communication receivers operating in MIMO/MISO environments, by signaling one or more values, e.g., data-to-pilot signal transmit power ratios and/or transmit antenna power distributions for the data and pilot signals.

摘要： A Generalized Rake (G-Rake) receiver is adapted for Golden code reception in a CDMA system. Signals transmitted by two or more transmit antennas are received at two or more receiver antennas. The signal from each receiver antenna is despread, and channel estimation is performed for each transmit antenna. G-Rake combining weights are calculated based on impairment correlation across G-Rake fingers and channel coefficients corresponding to each transmit antenna. The despread values from each symbol period are combined over a plurality of symbol periods based on the combining weights. The combined values are processed using coefficients derived from the Golden number to generate a set of decision variables, and the Golden encoded symbols are jointly detected from the decision variables. In some embodiments, spherical decoding and triangularization significantly simplify the decoding problem formulation.
