Abstract: | The technique of analyzing a set of channel parameters is discussed. Pseudorandom probing (for low-level noncorrelative interference with a typical user) and cross-correlation analysis are employed in the system described. The transfer function of this communications channel is convolved with the autocorrelation function of the probe signal; hence, analysis of the cross-correlation function at the receiver yields channel phase and amplitude parameters on a discrete basis. Implementation of these concepts with a demonstrable engineering model has been accomplished, and laboratory test results are presented. |
