WiBro (Wireless Broadband) is a mobile internet service in Korea based on IEEE802.16e standards. Since WiBro has moderate high data transmission rate and mobility over the metropolitan areas, it can be used for geo-location in the urban areas. There are various methods for conducting geo-location using WiBro system. In this paper TDOA (time difference of arrival) method is considered. TDOA measurement can be obtained at the receiver by detecting the RAS (radio access station) preamble. To perform multilateration geo-location, enough number of RAS needs to be detected. Since WiBro is based on cellular network, hearability enhancement is necessary to obtain enough number of RAS. Long integration method is commonly used for this process. In addition to integration, recursive interference cancellation method is used to mitigate CCI (cochannel interference). However, in multipath environment the recursive interference cancellation rule needs to be modified. In this paper, performance of WiBro geo-location after hearability enhancement and interference cancellation is analyzed in multi-path environment.
