ABSTRACT OF THE DISCLOSURE A diversity system comprising two receiving branches for receiving a radio signal including a data signal portion and a training signal portion propagating through a multipath, wherein, in each branch, a transmission property of a propagating path thereto is estimated from the training signal portion received, the transmission property comprising components significant to an equalizer and remaining insignificant components. A branch selectors selects, as a selected branch, a specific one of the branches according to the maximum value of a power ratio between the power of the significant components and of the insignificant components, and the equalizer equalizes the data signal portion received at the selected branch to produce an equalized signal as a resultant signal of the system. In order to reduce the effect of the property estimation from the data signal portion, the branch selector selects, as a selected branch, a particular one of the branches according to the maximum value of a power sum of the power of the significant components and the insignificant components, when another ratio of the power of the significant components and the power sum is larger than a predetermined value.
