摘要： The present invention provides a base station architecture that is modular in configuration, lowering the initial cost of implementing a new CDMA telecommunication system for a defined geographical region while allowing for future capacity. The scalable architecture is assembled from a digital base station unit that is configured to support a plurality of simultaneous wireless calls connecting to a conventional public switched telephone network. For initial startup, two base station units are deployed for redundancy in case of a single failure. Additional base station units may be added when the need arises for extra traffic capacity. If sectorization is required, the base station units may be directionally oriented. Coupled to and remote from each base station unit are two amplified antenna modules that contain an omni-directional or an external directional antenna, a high power RF amplifier for transmitted frequencies and a low noise amplifier for received frequencies. A separate power supply module capable of supporting two base station units provides continued service in the event of a mains power outage.
摘要翻译：本发明提供了一种模块化配置的基站架构，降低了为所定义的地理区域实施新的CDMA电信系统的初始成本，同时允许将来的容量。可扩展架构由数字基站单元组合，数字基站单元被配置为支持连接到常规公共交换电话网络的多个同时无线呼叫。对于初始启动，在单个故障的情况下，部署了两个基站单元以实现冗余。当需要额外的流量时，可以添加额外的基站单元。如果需要扇区化，则基站单元可以是定向的。耦合到每个基站单元并且远离每个基站单元的两个放大天线模块包含全向或外部定向天线，用于发射频率的高功率RF放大器和用于接收频率的低噪声放大器。能够支持两个基站单元的单独的电源模块在主电源中断的情况下提供持续的服务。

摘要： A communication station includes an antenna system having multiple antennas and delay units for receiving a transmitted signal and outputting a combined signal having a known distortion imparted by the antenna system. The combined signal is in turn processed by a modem, which compensates for the known distortion in a manner which provides improved signal gain. The improved signal gain permits a reduction in transmit power and, accordingly, increased capacity of the communication station. Where the antenna system is to be remotely located from related signal processing equipment, separate units for the RF receiver/transmitter and the other signal processing equipment are provided so that the RF receiver/transmitter may also be remotely located along with the antenna system.

摘要： A modem is configured for demodulating a communication signal associated with a unique code-division multiple access (CDMA) code. The modem includes an adaptive matched filter and a vector correlator. The vector correlator generates filter coefficients for the adaptive matched filter based on signal distortion determined by the vector correlator. The vector correlator has a processing capacity of at least eleven chips whereby the vector correlator compensates for a known phase distortion and for multipath distortion ascertainable within its processing capacity. The adaptive matched filter processes communication signals with the unique CDMA code using coefficients generated by the vector correlator.
