Patent number: 8331330Abstract: Techniques for efficient searching in asynchronous systems, such as W-CDMA, as well as multi-mode searching, are disclosed. In one aspect, step one and step three search are performed in a single search engine. In another aspect, a search engine is configurable to search the offsets of a slot in step one search, producing sequential hypothesis energies, and peak detecting and sorting those energies. In yet another aspect, the peak detector and sorter are configurable to perform step one searching or step three/multimode searching. Various other aspects of the invention are also presented. These aspects have the benefit of circuit area and search-time efficiency which translate into reduced costs, increased standby time, increased acquisition speed, higher quality signal transmission, increased data throughput, decreased power, and improved overall system capacity.Type: GrantFiled: April 20, 2010Date of Patent: December 11, 2012Assignee: QUALCOMM IncorporatedInventors: Daisuke Terasawa, Deepu John, Hao Liu, Qiuzhen (Joe) Zou, Sivarama Krishnan Venkatesan

Patent number: 7046701Abstract: A composite signal has two components, each carrying a stream of information that may be digital. In one application of a method according to an embodiment of the invention, at least one of the components is delayed such that a time relation between the streams of information is altered. The components are transferred via a common signal path such that upon transfer, the original time relation between the streams of information may be restored.Type: GrantFiled: October 9, 2001Date of Patent: May 16, 2006Assignee: Qualcomm Inc.Inventors: Mohammad J. Mohseni, Brian K. Butler, Deepu John, Haitao Zhang

Patent number: 6999500Abstract: A spreading system according to an embodiment of the invention spreads two data signals. The system produces a filtered signal that is based on one of the data signals and an output signal that is based on both of the data signals. In one example, a spreading system is used to perform QPSK spreading of two data signals, including separate processing of the two data signals, in a practical manner. Such separate control may include filtering and/or gain control.Type: GrantFiled: November 2, 2001Date of Patent: February 14, 2006Assignee: Qualcomm Inc.Inventors: Mohammad J. Mohseni, Brian K.

Patent number: 6687870Abstract: Interleavers are used in data transmission and storage applications to introduce diversity into a data stream, thereby making adjacent symbols more independent with respect to a transfer environment of variable quality. Conventional interleavers require storage in whole units of data blocks. This storage requirement complicates implementations for applications where available circuit area is limited and data rates and block sizes are large. A novel interleaver produces an interleaved data block using storage space that is only a fraction of the size of the input data block.Type: GrantFiled: September 23, 1999Date of Patent: February 3, 2004Assignee: Qualcomm, IncorporatedInventors: Jafar Mohseni, Brian Butler, Deepu John, Haitao Zhang

Patent number: 6615341Abstract: A digital signal processor (DSP) employs a variable-length instruction set. A portion of the variable-length instructions may be stored in adjacent locations within memory space with the beginning and ending of instructions occurring across memory word boundaries. The instructions may contain variable numbers of instruction fragments. Each instruction fragment causes a particular operation, or operations, to be performed allowing multiple operations during each clock cycle. The DSP includes multiple data buses, and in particular three data buses. The DSP may also use a register bank that has registers accessible by at least two processing units, allowing multiple operations to be performed on a particular set of data by the multiple processing units, without reading and writing the data to and from a memory. an instruction fetch unit that receives instructions of variable length stored in an instruction memory. An instruction memory may advantageously be separate from the three data memories.Type: GrantFiled: June 5, 2001Date of Patent: September 2, 2003Assignee: Qualcomm, Inc.Inventors: Gilbert C.
