摘要： A frequency and phase estimator simultaneously estimates the frequency and phase of an MPSK modulated signal with a frequency uncertainty range on the order of the symbol rate. The estimator defines a plurality of contiguous bands within the frequency uncertainty range of the signal, estimates the frequency to one of the bands, and utilizes the frequency estimate to derive a phase estimate. In a preferred embodiment, a plurality of signal samples of the frequency shifted signal in each of said bands are accumulated to produce a vector for each band, and the frequency estimate is selected in one of said bands, based upon the magnitude of the corresponding vector. The phase is estimated from the argument of the corresponding vector. The present invention is particularly suited for burst modems or TDMA systems, where frequency and phase estimates must be derived reliably from a limited number of incoming symbols at the beginning of each burst.
摘要翻译：频率和相位估计器同时估计具有符号率顺序的频率不确定范围的MPSK调制信号的频率和相位。估计器在信号的频率不确定性范围内定义多个连续频带，将频率估计为频带之一，并利用频率估计来导出相位估计。在优选实施例中，每个频带中的频移信号的多个信号样本被累积以产生每个频带的矢量，并且基于对应矢量的大小在所述频带之一中选择频率估计。相位根据相应向量的参数估计。本发明特别适合于突发调制解调器或TDMA系统，其中必须在每个突发开始时从有限数量的输入符号可靠地导出频率和相位估计。

摘要： In a method of determining a beam to be generated for a user, a user may be selected from a user population based on a parameter that is tracked for each user in the user population, and a beam preferred by the selected user may be determined. The preferred beam may be generated and used by a base station to transmit a pilot signal to the user population. Each user of the user population responds to the pilot signal. The base station may run a scheduling algorithm and schedule a user based on feedback received from all the users in the user population, and information may be transmitted to the scheduled user using the preferred beam.

The base station includes a steerable and adjustable multibeam antenna for communicating with each of the terminals, which have fixed antennas. A cell controller associated with each base station allocates communication time slots so as to minimize mutual interference between base station/terminal links sharing the same time slot. Slot assignment is based on regional, periodically updated interference measurements that are stored in data bases.

摘要： The method includes sending a request for permission to transmit by each ready node in the wireless network. Each ready node is a node of the wireless network ready to transmit, each request identifies a node in the network that is the destination, and each request is sent over a control channel. An iterative process based on priorities determined for the ready nodes is then performed to determine which ready nodes to block from transmission and which ready nodes to clear for transmission. Transmissions are sent over a payload channel from ready nodes in the clear to transmit state.
