Study of Correlation Coefficients of Complex Envelope and Phase in a Domain with Time and Frequency Axes in Narrowband Multipath Channel

摘要

As a basic multipath property required to allocate the pilot signal in orthogonal frequency division multiplexing (OFDM) and compose antennas in the multiple-input multiple-output (MIMO) technique, correlation coefficients of the complex envelope in the received signal level and phase in multipath channels were studied theoretically and by computer simulation in a domain with time, frequency, and space axes. First, correlation coefficient rho
