    • Systems and methods are disclosed which provide wireless communication systems implementing subsystems adapted for flexible deployment configurations and to resist the introduction of interference. Preferred embodiments of the present invention provide a wireless communication system configuration in which an ODU subsystem is coupled to an IDU subsystem using a fiber optic link. According to a preferred embodiment of the present invention, an ODU subsystem is adapted to provide conversion between digital and analog to thereby facilitate the use of a digital link between the ODU subsystem and a corresponding IDU subsystem. Embodiments of the present invention utilize a plurality of ODU subsystems configured according to the present invention to provide wireless communication coverage of a service area, such as to provide a wireless application termination system (WATS) hub for use in providing wireless communication links with respect to a plurality of subscriber units.

    • An adaptive forward error correction system for mitigating interference and fading in RF data transmissions has a hub and subscriber stations transmitting and receiving forward error correction encoded data packets. The hub and subscriber stations count codewords and/or packets received with errors. The hub calculates a type of quality measure using the counts and compares this measure to quality thresholds. If an upper threshold is exceeded, the hub increases a size of transmitted active data fields and decreases a size of blank data fields. If a lower threshold is not met, the hub decreases a size of transmitted active data fields and increases a size of blank data fields. Similar changes by subscriber stations are directed by the hub. These changes are coordinated in headers associated with the packets or codewords, via a separate control channel or multi cast via a data stream used for transmitting the data packets.
    • 用于减轻RF数据传输中的干扰和衰落的自适应前向纠错系统具有集线器和用户站发送和接收前向纠错编码数据分组。 集线器和订户站对错误接收的码字和/或数据包进行计数。 集线器使用计数器计算质量度量的类型,并将此度量与质量阈值进行比较。 如果超过上限阈值,则集线器增加传输的有效数据字段的大小,并减小空白数据字段的大小。 如果不满足较低的阈值,则集线器减小传输的活动数据字段的大小,并增加空白数据字段的大小。 用户站的类似更改由集线器指导。 这些改变通过经由单独的控制信道或通过用于发送数据分组的数据流的多播来与分组或码字相关联的报头进行协调。
