Abstract:
PURPOSE: An adaptive transmission signal detecting method and an apparatus thereof are provided to efficiently detect a transmission signal by controlling the quantity of calculation. CONSTITUTION: A receiver receives a reception signal vector(S100). The receiver presumes a channel matrix(S110). The receiver performs QR analysis based on the presumed channel matrix(S120). The receiver calculates division spaces based on SNR(Signal to Noise Raito) or SINR(Signal-to-Interference Noise Ratio)(S130). The receiver detects an ML(Maximum Likelihood) point within the division space(S140). The receiver restores a transmission signal vector(S150).
Abstract:
PURPOSE: A location information transmission method of a base station and a device thereof are provided to transmit the location information of the base station to a terminal using the passive different kind access system detection method thereby selecting the base station of the optimized different kind access system in the terminal. CONSTITUTION: A location information transmission device of a base station constitutes the frame including heterogeneous access system information(S401). Based on interworking technology with the different kind access system or backbone, the location information transmission device extracts location information of the base station of the different kind access system in a serving BS(Base Station)(S402). The location information transmission device inserts the extracted BS location information and a BS type to a frame(S403). The location information transmission device of the base station transmits the frame to a terminal(S404).
