Aspects describe a Highly Detectable Pilot that allows a mobile device to detect more base stations and, thus, can provide more accuracy in location estimate. The computing system design of one application of the present invention includes an instruction pipe having a decompression circuit, a reprogrammable logic unit and a data bus. A weighting coefficient calculating unit calculates weighting coefficients based on SNR values as transmission line information from an SNR calculating unit and sends calculated weighting coefficients to a multiplier, where phase correction values based on the reference phase information are multiplied by the weighting coefficients to be correction coefficients. When the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas.
