Abstract:

Several techniques for reducing the error in the transmission of continuous information are investigated. In self-contained appendixes, the following topics are studied Coding Networks, Predictive Coding, ForcedErasure Decoding, Mappings, Channel Characterization and Simulation Techniques, and Code Construction. The minimum mean-square errors in some systems that transmit and process continuous information by solely linear operations are compared with the absolutely minimum mean-square error predicted by information theory. The linear encoding of sampled data is also studied. Several results relating to the erasure reconstruction spectrum of generalized group codes are derived. Both the evaluation difficulties of and the future study directions of Forced-Erasure Decoding are discussed. The performance of certain information sources is calculated. A hybrid system for transmitting sampled data is also studied. Techniques for the digital simulation of stochastic processes are discussed and some investigations are suggested. Generalizations of code construction techniques were also studied. The value of these techniques is in hybrid coding situations. Author
