摘要： A communications system and method for exchanging spectrum usage information through a drop box (100) includes one or more central stations (101) that defines a region of operation. A central drop box (102) is associated with the central station (101) for providing a database of spectrum usage information. Stations (103, 105, 107) using the communications system may submit information regarding spectrum usage to the central drop box (102) that affects the region of operation (109, 115) for providing the most efficient and non-interfering uses of the frequency spectrum.

摘要： During operation of a secondary communication system, nodes having different channel monitoring capabilities or requirements will cooperatively monitor possible frequencies for transmissions, each node using only a subset of all possible modulation sensing schemes. All nodes will share channel occupancy information to other nodes within the communication system. For example, a first group of nodes may monitor possible frequencies for television transmissions, while a second group of nodes may monitor the possible frequencies for APCO 25 transmissions. A group of nodes may also cooperatively monitor possible frequencies for more than one type of modulation transmission. Channel information will be shared among the nodes.

摘要： A method and apparatus for reducing inter-modulation within a wireless communications device (100) is provided herein. During operation a wireless communications device will perform frequency analysis on a received signal (125) to determine if any undesirable IM products exist. If undesirable IM products exist, the incoming signal is attenuated by adjusting an automatic-gain control (AGC) threshold for AGC circuitry (101, 107). By adjusting the AGC threshold, the incoming signal will be attenuated at lower gain values, reducing the amount of IM present within the wireless communications device.
摘要翻译：本文提供了一种用于减少无线通信设备（100）内的互调的方法和装置。在操作期间，无线通信设备将对接收到的信号（125）执行频率分析，以确定是否存在任何不期望的IM产品。如果存在不期望的IM产品，则通过调整AGC电路（101,107）的自动增益控制（AGC）阈值来衰减输入信号。通过调整AGC阈值，输入信号将以较低增益值衰减，减少了无线通信设备内存在的IM量。
