一种可配置的蜂窝式终端引擎(CTE)可由外部代理(例如，微控制器、DSP或状态机)来配置以适应不同扩频系统的特定需求。该CTE在芯片组上包括调制解调器单元和信道编解码器单元。所述调制解调器单元具有前端单元(102)，其用于连接到天线；匹配的滤波器搜索器单元(104)，其至少被连接至所述前端单元；搜索器单元(106)，其至少被连接至所述前端单元；分路处理单元(108)，其被连接至所述前端单元；参数估算处理器单元(110)，其至少被连接至所述分路处理单元和所述搜索器单元；以及发射机单元(112)。所述信道编解码器单元具有信道解码器单元(118)，其至少被连接至所述分路处理单元；以及信道编码器(120)，其至少被连接至所述发射机单元。 A configurable cellular terminal engine (CTE) in accordance with an exemplary embodiment of this invention is configurable by an external agent (e.g., microcontroller, DSP, or state machine) to suit the particular requirements of different spread spectrum systems. In an exemplary embodiment, the CTE comprises on a chipset a modem unit and a channel codec unit. The modem unit has a front end unit for coupling to an antenna; a matched filter searchers unit coupled at least to the front end unit; a searchers unit coupled to at least the front end unit; a finger processing unit coupled to the front end unit; a parameter estimation processor unit coupled to at least the finger processing unit and the searchers unit; and a transmitter unit. The channel codec unit has a channel decoder unit coupled at least to the finger processing unit; and a channel encoder coupled at least to the transmitter unit.
