摘要： Apparatus and methods are disclosed for providing fine timing assistance to global navigation satellite systems (GNSS) via wireless local area network (WLAN). In one embodiment, a method (300) for synchronizing a global navigation satellite system (GNSS) receiver includes receiving (308), by a wireless device, via a wireless local area network (WLAN), fine time assistance information transmitted by an assisting device connected to the WLAN. A time value of a GNSS clock of the wireless device is adjusted (312) based on the fine time assistance information. Based on the adjusted time value, GNSS codes of a GNSS positioning signal are acquired (314) by the wireless device.

摘要： A method and system for generating a set of candidate symbols. A system includes a Multiple Input Multiple Output ("MIMO") receiver (2202). The receiver includes a candidate generation look-up table ("LUT") (2206) that provides a list of candidate values for a transmitted symbol selected from a constellation of symbols. The candidate generation LUT stores candidate lists for a portion of the constellation of symbols. The portion of the constellation for which candidate lists are stored is selected according to a symmetry of the constellation. The LUT preferably provides a secondary constellation superimposed on a decision region of a primary constellation. The LUT also preferably includes an inner point of the primary constellation and outer points of the primary constellation. The primary and secondary constellations are preferably compressed by application of quadrant, mirror, and inner-point symmetries.

摘要： Disclosed herein is a system and method for determining the presence of rotated-BPSK modulation. In addition, disclosed herein is a system and method for determining if a received packet (502) is a Legacy (516), Mixed-Mode (520), or Green-Field packet (510) in accordance with the determination of the presence of rotated-BPSK modulation. The presence of a Green- Field packet may be determined by detecting if additional tones are being excited in an LTF symbol of the received packet and/or if a SIG field symbol following the LTF symbol is modulated by rotated-BPSK. The presence of a Mixed-Mode packet may be determined by detecting if the first four bits of the SIG field symbol following the LTF symbol are [1 1 0 1] (514) and/or detecting if a symbol following an L-SIG symbol is modulated by rotated-BPSK (518). The presence of a Legacy packet may be determined by detecting if the symbol following the L-SIG symbol is modulated by BPSK.
摘要翻译：本文公开了一种用于确定旋转BPSK调制的存在的系统和方法。此外，本文所公开的是一种系统和方法，用于根据确定是否存在接收到的分组（502）是否为传统（516），混合模式（520）或绿色场分组（510）旋转BPSK调制。可以通过检测附加音调是否在接收到的分组的LTF符号中被激励和/或如果通过旋转BPSK调制LTF符号之后的SIG字段符号，则可以确定绿场分组的存在。混合模式分组的存在可以通过检测LTF符号之后的SIG字段符号的前四位是否为[1 1 0 1]（514）和/或检测是否符合L-SIG符号的符号来确定由旋转BPSK调制（518）。可以通过检测L-SIG符号之后的符号是否被BPSK调制来确定遗留分组的存在。

摘要： A Multiple-Input Multiple-Output (MIMO) receiver (104) is provided. The MIMO receiver comprises a parameterized sphere detector (114) having two search modes. During a first search mode, the parameterized sphere detector enumerates a number of best candidate vectors up to a fixed parameter value. During a second search mode, the parameterized sphere detector enumerates additional candidate vectors using a greedy search until a predetermined number of candidate vectors have been enumerated.
