PURPOSE:To execute good data transmission by preventing inter-symbol interfer ence or inter-channel interference in the data transmission between a mobile station moving at high speed and a base station. CONSTITUTION:Four pieces of transversal filters 11 to 14 are provided, and also, synchronizing patterns added to each slot in an input signal outputted from a first and a second synchronous detectors 1,2 are checked, and in the case that a transmission characteristic between two communicating stations is deteriorated, the equivalent transmission characteristic between two stations is estimated in a short time, and also, the tap coefficients cn, en, dn, fn of each above-mentioned transversal filter 11 to 14 are set 8 to the optimum values to meet the above-mentioned transmission characteristic on the basis of the above-mentioned estimation so as to suppress the inter-symbol interference or the inter-channel interference. |
