摘要： The present invention provides for a method that could be advantageously implemented in a satellite local area network (LAN) in which an average number of sites share a TDMA link. The invention provides for both a dedicated bandwidth to all the sites and a shared bandwidth that is dynamically assigned to the sites, therefore allowing for both synchronous traffic and for on request burst mode traffic. The method includes a reservation method of this shared bandwidth which is specially optimized for a satellite link. The method provides also for a network that automatically managed its communication bandwidth resources and the synchronization of the sites, without the need of an external controller. The present invention also provides for a satellite modem to transmit data from a site, to receive data from the sites and to manage the bandwidth resources of the TDMA satellite in accordance with the above method.

摘要： Generalized circuit topology of voltage level multiplier modules (VLMMs) for use with multilevel inverters (MLIs) and power converter circuits comprising at least one VLMM and a MLI are described herein. The VLMM is configured to receive a first output voltage from the MLI having a first number of voltage levels and to generate a second output voltage having a second number of voltage levels. If the first number of voltage levels is M, and the VLMM is N-fold voltage level multiplier, then second number of voltage levels is MxN+1. Switching pattern generators for use with the VLMM and modulation methods for controlling switching elements of the VLMM are also described herein.

摘要： Wireless communications have become ubiquitous for society with the availability of low cost front end transmitter and receiver circuits. Network operators strive to provide wireless signals with good Signal to Noise and Interference Ratio (SNIR) whilst increasing useable network capacity and bandwidth using maximum over-the-air data rate and controlling or minimizing over-the-air congestion. Historically this has been achieved via evolutions of network and consumer hardware, firmware, software and hence it would be beneficial to provide network operators with a means of increasing network capacity without requiring either additional hardware complexity and / or additional computational complexity in the receiving devices. The inventor has established a new domain within the network, the spreading code domain, to increase the data rate, by using spreading codes to map the data in conjunction with the constellation symbols and reduce the amount of transmitted data required.
摘要翻译：随着低成本前端发射机和接收机电路的可用性，无线通信已经成为社会普遍存在的。网络运营商努力为无线信号提供良好的信噪比和干扰比（SNIR），同时利用最大的空中数据速率增加可用的网络容量和带宽，并控制或最小化空中拥塞。历史上，这是通过网络和消费者硬件，固件，软件的发展来实现的，因此，为网络运营商提供增加网络容量的手段将是有益的，而不需要额外的硬件复杂性和/或接收设备中额外的计算复杂度。本发明人已经在网络内建立了一个新的领域，扩展码域，通过使用扩频码与星座符号一起映射数据，并减少所需传输的数据量来增加数据速率。

摘要： An image registration method is disclosed for processing a distorted image into a registered image that is aligned with reference to an original image. Distortions from the original image may include scaling, rotation, and noise. The method is based on correlating Radon transforms of both images to determine the rotation angle, and the scaling factor is determined by dividing averages of the overall luminance of each image on the assumption that any added noise will cancel. The Fast Fourier Transform (FFT) is used to estimate global spatial shifts. In one embodiment, the distorted image is first scaled to the size of the original image before being rotated. In another embodiment, the original image is first scaled to the size of the distorted image before rotating the distorted image, and finally scaling it to match the original image. A corresponding system for image registration is also provided.
摘要翻译：公开了一种用于将失真的图像处理成参照原始图像对准的注册图像的图像配准方法。原始图像的变形可能包括缩放，旋转和噪声。该方法基于将两个图像的Radon变换相关联以确定旋转角度，并且通过在假定任何附加噪声将被取消的情况下对每个图像的总亮度的平均值进行除法来确定缩放因子。快速傅里叶变换（FFT）用于估计全局空间位移。在一个实施例中，失真的图像首先在旋转之前缩放到原始图像的尺寸。在另一个实施例中，首先将原始图像缩放到失真图像的大小，然后旋转失真图像，最后缩放它以匹配原始图像。还提供了一种用于图像配准的相应系统。
