摘要： A method for radar protection. The method includes recording energy events and calculating differences in recorded energy events to determine pulses. The method further includes sorting intervals between pulses into histogram bins, each bin representing a range of time intervals between two pulses, each pulse indicative of a radar frequency and limiting network traffic on a frequency based on a selected bin count.

摘要： A wireless access point selection system. In particular implementations, a method includes receiving a notification that identifies a wireless access point that detects radar on an operating channel and identifies the operating channel; updating neighbor lists of one or more neighboring wireless access points to remove the wireless access point from the neighbor list, where the neighbor list comprises neighbor wireless access points, corresponding operating channels, and corresponding enable indications, where each enable indication indicates if a channel availability check is required before performing active scanning; and transmitting the updated neighbor list to the neighboring wireless access points. In one implementation, a system provides a DFS enable indication to wireless clients so they can know whether a channel availability check is required prior to transmitting.

摘要： A method for detecting a signal having random characteristics. A plurality of bursts are detected within a predetermined time period. The plurality of bursts are evaluated to determine how many pulses each of the plurality of bursts contains. The signal having random characteristics is present responsive to the ratio of number of bursts containing a first predetermined number of pulses being approximately equal to number of bursts containing a second predetermined number of pulses. For signals such as a Bin-5 Test Signal, the signal is determined to be present responsive to the number of singletons (bursts having one pulse), the number of pairs (bursts having two pulses) and the number of triplets (bursts having three pulses) being approximately equal.

摘要： An external primary spectrum user detector (ESUD) is used to take over the role of integral radar detectors, and relieve user devices of the constraints associated with Primary Spectrum User detection. The ESUD can establish a relationship with the user devices by means of a cryptographic signature. The ESUD installation includes assigning it a frequency band to scan for primary spectrum user signals and the type of signals to be detected. Once activated, the ESUD will scan its assigned frequencies and emit to types of messages, “All Clear” and “Primary Spectrum User detected.” User devices on the network listen for the ESUD messages. In the absence of messages from the ESUD, the user devices activate their internal primary spectrum user detectors until ESUD messages are received.

摘要： Described in an example embodiment herein is a procedure that comprises sampling one or more channels that are not in use for a short time at certain intervals. In particular embodiments, the interval duration is irregular so as to prevent “out of step” lock with a radar's pulses. During the sampling period, detection events are stored in terms of start time and duration. If potential radar events are detected, the channels are sampled for a longer, second interval to determine whether the detection events are indicative of radar. The length of the sampling period determines the number of samples needed to get an acceptable detection probability.
摘要翻译：在本文的示例性实施例中描述的是包括以特定间隔对短时间内未使用的一个或多个信道进行采样的过程。在具体实施例中，间隔持续时间是不规则的，以便防止雷达的脉冲“失步”锁定。在采样期间，检测事件以开始时间和持续时间存储。如果检测到潜在的雷达事件，则通道被采样更长的第二时间间隔，以确定检测事件是否指示雷达。采样周期的长度决定了获得可接受的检测概率所需的样本数。
