摘要： A repeated integral images method filters image data in only two passes, e.g., the first pass filters horizontal rows of pixels and a second pass filters vertical columns of pixels, or in a single pass. The filter performs at least one infinite impulse response (IIR) filter and at least one finite impulse response (FIR) filter on the image data. A plurality of IIR filters and FIR filters maybe performed to approximate a Gaussian filter. By minimizing the number of passes, the data flow between the processing unit and the storage unit is greatly reduced compared to conventional repeated integral images method thereby improving computation time.

摘要： Techniques for dynamically managing receiver resources to achieve good latency and throughput performance are described. A receiver may have various types of receiver resources such as demod resources for demodulating packets, decode resources for decoding packets, packet processing resources, etc. These various types of receiver resources may be dynamically assigned to packets. In one design, receiver resource usage by each packet to be processed by the receiver may be estimated. The available receiver resources may be assigned to packets based on the estimated receiver resource usage by each packet and one or more assignment criteria such as priority, latency requirements, etc. The latency of each packet may be determined based on the receiver resource assignment. If the latency requirements of any packet are not met, then receiver processing may be skipped or deferred for one or more packets such that the latency requirements of each packet to be processed can be met.

摘要： The disclosure is directed to techniques for picture-in-picture (PIP) processing for video telephony (VT). According to the disclosed techniques, a local video communication device transmits PIP information to a remote video communication device. Using the PIP information, the remote video communication device applies preferential encoding to non-PIP regions of video transmitted to the local video communication device.

摘要： A method is provided for compensating for clock drift error and movement error of an access terminal. A forward link error is obtained that is attributable to at least a first error (e.g., clock drift error) component and a second error (e.g., movement error) component. The first error component and the second error component are estimated based on the obtained forward link error. A receive clock of the access terminal is compensated based on a combination of the first error component and the second error component. A transmit clock of the access terminal is compensated based on a difference between the first error component and the second error component. The forward link error may include a timing synchronization error between the access terminal and an access point as well as a frequency synchronization error between a forward link frequency and a baseband reference frequency.

摘要： Techniques for encoding a phase adjustment for a feedback signal in a closed-loop transmit diversity system. In an aspect, codewords for the phase adjustments are chosen according to a variable-length prefix code. The prefix code aspect allows the codewords to be transmitted in sequence on the feedback channel without being separated by “commas” or demarcation symbols. The variable-length aspect provides a variety of coarse and fine phase adjustment quantization step sizes to accommodate multiple different channel scenarios. In an aspect, the length of the codewords may be further optimized according to the Huffman encoding algorithm.

摘要： Techniques for efficiently decoding packets sent with H-ARQ are described. Packet decoding for H-ARQ may be performed based on local search around a start of packet (SOP) decision for a packet. The SOP decision for the packet may be made based on traffic detection results for received transmissions. At least one SOP hypothesis may be determined for the packet based on the SOP decision, and the received transmissions may be decoded based on the at least one SOP hypothesis. A sliding SOP window may be used to keep track of SOP hypotheses for the packet. The sliding window may be initialized at an earliest received transmission, moved forward for each subsequent received transmission with no detected packet data, and maintained at the first received transmission with detected traffic. Rotating buffers may be used to store received transmissions for packets for decoding.

摘要： Aspects described a low receiver complexity approach for reliable packet decoding when Hybrid ARQ protocol is employed with persistent assignment and potentially an erasure sequence transmission. Multiple hypotheses packet decoding performance is achieved while mitigating multiple hypotheses receiver complexity. A reference number is utilized to perform hypotheses. The reference number is independent of a start of packet. A sequence of reference numbers can be utilized, which may not necessarily be sequential numbers. The reference numbers are pre-defined.
