JTAPI是由Sun公司提出的基于Java语言的应用程序接口。由于JTAPI是基于Java的应用接口，使得JTAPI的对象独立于操作系统和硬件平台，支持跨平台的应用。JTAPI定义了一套类库，包含电话功能和扩充功能。JTAPI结合了传统的电话服务和Web处理能力，具有较强的功能。但是，基于Java的特性，使得JTAPI在拥有强大功能的同时，也失去了普及和推广的基础。-JTAPI by Sun"s Java language on the application program interface. As JTAPI is a Java-based application interface, JTAPI makes the object independent of operating systems and hardware platforms to support cross-platform applications. JTAPI definition of a set of class libraries, including telephone functions and expansion capabilities. JTAPI combination of traditional telephone services and Web processing capability, and a strong function. However, based on Java, which makes JTAPI the powerful functions, lost popularize and promote the foundation.

This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder). You should run "Simulation.m" function that include all modules.
