Abstract
In this paper, average frequency correlation and root-
mean-squared (rms) delay spread estimation for wireless
communication systems are described. A practical algo-
rithm for averaged channel frequency correlation estima-
tion, which can be used for measuring frequency selectivity,
is given. Average rms delay spread of the channel is ob-
tained directly from the channel frequency correlation es-
timate without obtaining the channel power delay profile
(PDP). Analytical relations between channel frequency cor-
relation and rms delay spread value is derived by assum-
ing an exponentially decaying PDP. Robustness of the pro-
posed rms delay spread estimation method for other PDPs
is evaluated. An orthogonal frequency division multiplexing
(OFDM) based wireless communication system is consid-
