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.

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： The present invention provides a versatile system for selectively spreading carrier data across multiple carrier paths within an Orthogonal Frequency Division Multiplexing (OFDM) system (200), particularly an ultra-wideband (UWB) system. The present invention provides a data input (202), which passes data to a randomizer (204). The data then passes to a convolutional code function (206), the output of which is punctured by puncturing function (208). An interleaver function (210) receives the punctured code data, and cooperatively operates with a mapper element (218) to prepare the coded data for pre-transmission conversion by an IFFT (220). The mapper element (218) comprises a dual carrier modulation function (216), which associates and transforms two punctured code data elements into a format for transmission on two separate signal tones.

摘要： Systems and methods for providing multiple-input multiple-output (MIMO) detection, comprising a leaf node predictor (310) for receiving a processed communications stream, computing at least one channel metric corresponding to the communications stream for a given channel realization by optimizing a predetermined probability, and analytically generating at least one parameter to output, which at least one parameter corresponds to at least one predicted best leaf node candidate for the given channel realization.
