Abstract

Today's base station architectures are mainly based on digital signal processing (DSP) tech- niques. The receiver back-end, the exciter front-end and the complete audio processing is often realized in DSP hardware and software. The introduction of this new technology in communication equipment is forced by rapidly falling prices compared to analog technologies. Whereas the prices for DSP compo- nents are falling linearly over time the prices for analog components tend to decrease much slower.

DIGITAL VOICE MEMORY FOR BASE STATIONS STATUS REPORTING

by Gotlfried Neuhaus and Norbett Roettger

1. GENERAL

  Today's base station architectures are mainly based on digital signal processing (DSP) tech- niques. The receiver back-end, the exciter front-end and the complete audio processing is often realized in DSP hardware and software. The introduction of this new technology in communication equipment is forced by rapidly falling prices compared to analog technologies. Whereas the prices for DSP compo- nents are falling linearly over time the prices for analog components tend to decrease much slower.

  In addition, at the end of the 20th century the customers expect "easy to use" interfaces to the new technical equipment being used.

  Figure 1 shows the principle block diagram of a base station equipped with a digital voice memory system based on the above mentioned DSP technol- ogy. The arrows show the status message informa- tion exchange between the "voice memory system" and the other functional blocks within the base sta- tion.

The status messages are for example:

power amplifier: line interface: - power failure - line loss failure - forward/revert - line check failure

2. VOICE MEMORY SYSTEM

  The voice memory system contains a set of sampled human voice status messages. When the status received from one of the modules changes its state, the voice memory system generates a voiced status message over the air to the subscriber units and d...
