摘要： The present invention relates to a communication system and method for transmitting sync flags and pilot symbols during sync symbol periods. Example embodiments provide a method for sharing sync symbols to communicate flag sequences and pilot sequences during a sequence of sync symbol periods. The method includes modulating the pilot sequence by multiplying a pilot code by each value of the pilot sequence, and modulating the flag sequence by multiplying a flag code by each value of the flag sequence. The pilot and flag codes are mutually orthogonal to each other and each includes at least two non-zero values. The method further includes generating a resulting sync symbol sequence based on the modulated pilot sequence and modulated flag sequence, and sending the resulting sync symbol sequence during the sync symbol period.

摘要： An access node of a communication system is configured to control crosstalk between channels of the system. Vectoring circuitry in the access node estimates crosstalk between channels of the system, generates a compensation matrix based on the crosstalk estimates, and generates compensated signals based on the compensation matrix. The compensation matrix, which may be a precoder matrix or a postcoder matrix, is generated using a multiplicative update process in which a previous version of the compensation matrix comprising one or more non-zero off-diagonal elements is updated by at least one of pre-multiplying by a first auxiliary matrix and post-multiplying by a second auxiliary matrix, with a given one of the auxiliary matrices also comprising one or more non-zero off-diagonal elements. The compensated signals may be pre-compensated signals or post-compensated signals.

摘要： A base station of a code division, multiple access (CDMA) telecommunications system employs scheduling of data transmission signals to corresponding user transceivers in down-link channels of a data network. One or more user transceivers may be in communication with a base station within a cell, and each user may have a minimum data rate requirement. In accordance with the present invention, the scheduling of user data transmission follows the constraints that 1) each base station transmits to user transceivers one at a time, and 2) the base station uses full available power for the down-link channel when transmitting (for data networks only). Given a data network of users, the method of scheduling and data rates may be modeled in accordance with a linear programming problem optimized according to a predefined criterion. In addition, the present method may be employed in a hybrid CDMA/time-share system to reduce power of data channels in communication with user transceivers near the base station. A continuum of rates may be achieved based on the system signal to interference ratio (S/I). The error rate requirement of a user's down-link channel may be met provided the S/I of the channel is greater than a predetermined threshold value.
摘要翻译：码分多址（CDMA）电信系统的基站采用将数据传输信号调度到数据网络的下行链路信道中的相应用户收发信机。一个或多个用户收发器可以与小区内的基站通信，并且每个用户可以具有最小数据速率要求。根据本发明，用户数据传输的调度遵循以下约束：1）每个基站一次一个地发送给用户收发机，以及2）当发送时基站使用下行链路信道的全部可用功率（仅用于数据网络）。给定用户的数据网络，调度和数据速率的方法可以根据根据预定标准优化的线性规划问题来建模。此外，本方法可以用在混合CDMA /时分共享系统中以减少与基站附近的用户收发机通信的数据信道的功率。基于系统信号与干扰比（S / I）可以实现连续的速率。只要信道的S / I大于预定阈值，就可以满足用户下行链路信道的错误率要求。

摘要： Techniques and systems for planning of wireless networks are described. A system according to an aspect of the present invention receives inputs describing traffic statistics for a wireless network and computes network specifications. The system uses the traffic statistics and network specifications as inputs to a computationally tractable model used to compute parameters for the user level performance of the wireless network. The model may suitably be a processor sharing queuing model. The model employed by the planning system allows analytical solution for the desired user level parameters, given the characteristics and conditions entered as inputs and the intended network layout characteristics. Once a set of user level performance parameters has been computed, the values of the parameters are examined to determine if they meet predetermined requirements, in an iterative process continuing until a set of specifications has been developed that produces parameters meeting the requirements.

摘要： Various methods and devices are provided to address the need for improved data transmission with coherence interval user selection. In one method, a transmit group to which to transmit during a first coherence time interval is selected. The transmit group is selected (101) from a plurality of users for which there is data to transmit during the first coherence time interval. The data associated with users in the transmit group is transmitted (102) to the transmit group during the first coherence time interval. Subsequent transmit groups to which to transmit during subsequent coherence time intervals are also selected (103). A user of the plurality of users is selected for transmission over the course of the first coherence time interval and the subsequent coherence time intervals with a predetermined probability.
