Claim:
1. A receiving apparatus in a wireless environment, the receiving apparatus comprising: a channel estimator configured to determine a channel response between the receiving apparatus and a transmitting apparatus by using a first signal received from the transmitting apparatus; a statistical signal generator configured to generate a plurality of second signals by respectively adding a plurality of arbitrary signals to the determined channel response, wherein a characteristic of each of the plurality of second signals is statistically identical to a characteristic of the first signal; an adaptive algorithm processor configured to determine a filter coefficient by performing an adaptive equalization algorithm based on the plurality of second signals and the plurality of arbitrary signals, and to determine the filter coefficient within a predetermined time in an environment where channel change frequently occurs; and a main filter configured to generate an output signal by filtering the first signal based on the determined filter coefficient, wherein each of the plurality of arbitrary signals is a binary sequence, wherein the predetermined time is required for determining an optimized filter coefficient, and wherein the first signal is a training signal for determining the channel response.
