摘要： A wireless communication device processes N Radio Frequency (RF) bursts contained within N slots of a digital communications time divided frame, wherein N is a positive integer greater than one. The wireless communication device includes an RF front end, a baseband processor, and an equalizer module. The RF from end is operable to receive the plurality of received RF bursts and to convert the RF bursts to corresponding baseband signals. The baseband processor operably couples to the RF front end, is operable to receive the baseband signals, is operable to pre-equalization process the baseband signals to produce processed baseband signals, and is operable to post-equalization process soft decisions. The equalizer module operably couples to the baseband processor and is operable to equalize the processed baseband signals to produce the soft decisions. These RF bursts may be contained in adjacent slots or, in non-adjacent slots, or in a combination of adjacent slots and non-adjacent slots.

摘要： A TDMA wireless communication system adjusts the power control target and transmission power based upon link quality to enhance voice capacity. The power can be adjusted in response to the average SNIR and number of decoding errors in a link quality reporting period. The power control target can be increased and decreased in discrete intervals after evaluating the number of decoding errors in the reporting period. The transmission power can be adjusted towards the new power control target based upon the average SNIR.

摘要： A baseband processing module for use within a Radio Frequency (RF) transceiver includes a downlink/uplink interface, TX processing components, a processor, memory, RX processing components, and a turbo decoding module. The RX processing components receive a baseband RX signal from the RF front end, produce a set of IR samples from the baseband RX signal, and transfer the set of IR samples to the memory. The turbo decoding module receives at least one set of IR samples from the memory, forms a turbo code word from the at least one set of IR samples, turbo decodes the turbo code word to produce inbound data, and outputs the inbound data to the downlink/uplink interface. The turbo decoding module performs metric normalization based upon a chosen metric, performs de-rate matching, performs error detection operations, and extracts information from a MAC packet that it produces.

摘要： A method for processing signals in a communication system is disclosed and may include pipelining processing of a received HSDPA bitstream within a single chip. The pipelining may include calculating a memory address for a current portion of a plurality of information bits in the received HSDPA bitstream, while storing on-chip, a portion of the plurality of information bits in the received HSDPA bitstream that is subsequent to the current portion. A portion of the plurality of information bits in the received HSDPA bitstream that is previous to the current portion may be decoded during the calculating and storing. The calculation of the memory address for the current portion of the plurality of information bits may be achieved without the use of a buffer. Processing of the plurality of information bits in the received HSDPA bitstream may be partitioned into a functional data processing path and functional address processing path.

摘要： An on-demand message system includes a profile proxy server and a plurality of message servers coupled to a wireless network for sending messages to mobile users under conditions specified by the users and sellers. Users provide profile information specifying categories and conditions for which they will receive messages. Sellers also provide profile information specifying conditions under which they want messages to be sent. A multicast message is sent and processed by target users in response to a predetermined event, e.g., location update, conveying information related to a seller for which the target users have expressed an interest in receiving.
