摘要： An appliance facilitates localization of a station (STA) in a network, for example, a short-range wireless network. An automatic response to a request for a measurement related communication is provided. The appliance can include a radio frequency (RF) interface and a media access control (MAC) section. The MAC section can receive the request and generate the automatic response immediately after a uniform period that is uniform among any such appliance within the network. The appliance performs only the generation of the automatic response, though the response can include additional information such as (x, y) coordinates of the appliance.

摘要： Noise and interference can be independently measured in a multiple user Orthogonal Frequency Division Multiplexing (OFDM) system. Co-channel interference is measured in a frequency hopping, multiple user, OFDM system by tracking the sub-carriers assigned to all users in a particular service area or cell. The composite noise plus interference can be determined by measuring the amount of received power in a sub-carrier whenever it is not assigned to any user in the cell. A value is stored for each sub-carrier in the system and the value of noise plus interference can be a weighted average of the present value with previously stored values. The noise component can be independently determined in a synchronous system. In the synchronous system, all users in a system may periodically be prohibited from broadcasting over a sub-carrier and the received power in the sub-carrier measured during the period having no broadcasts.
摘要翻译：噪声和干扰可以在多用户正交频分复用（OFDM）系统中独立测量。通过跟踪分配给特定服务区域或小区中的所有用户的子载波，在跳频，多用户OFDM系统中测量同信道干扰。复合噪声加干扰可以通过在子载波中没有分配给小区中的任何用户时测量子载波中的接收功率的量来确定。为系统中的每个子载波存储一个值，并且噪声加干扰的值可以是具有先前存储的值的当前值的加权平均值。噪声分量可以在同步系统中独立确定。在同步系统中，系统中的所有用户可以周期地禁止通过子载波进行广播，并且在没有广播的时段期间测量的子载波中的接收功率。
