In this work we consider the problem of estimation of the location parameter of certain distributions

with known coe_cient of variation by U-statistics. We discussed the general technique of estimating

the location parameter of a distribution with known coe_cient of variation using the theory of Ustatistics.

The method has been illustrated in obtaining the estimator of the location parameter

(mean) of normal, logistic and double exponential distributions. The e_ciency properties of our

estimator in each case when compared with certain other commonly available estimators are also

discussed.
