Abstract:

The symposium was divided into five principal areas Data Compression methods as related to particle count data and the transmission of imagery. Evaluation of image compression schemes included. Digital Techniques covering efficient bandwidth utilization, delta modulation and Phase Shift Keyed receiver techniques. Included are adaptive techniques covering filtering, Fast Fourier Transform processor, sampled-data FM demodulator and transmission equalization. Satellite Communications treats propagation and system considerations of the tactical environment ground terminal measurements related to link signalling, spread spectrum multiple access and frequency and orbit utilization. System Considerations discusses automatic message switching and traffic handling, message processing facility and technical control, transmission performance and technical and economic considerations of digitalanalog communications. Interference covers generation, detection and control related to telecommunications. Author
