摘要
A method, using a positioning module and a wireless telecommunication network comprises first and second base stations and first and second mobile terminals, said first terminal comprising a rake receiver, the method comprising:storing received signal data (MT_data) generated by the first mobile terminal rake receiver from signals transmitted over the air in a multipath environment and received by first mobile terminal;storing positioning data (MT_pos) obtained from the positioning module, said positioning data (MT_pos) comprising a plurality of positions of first mobile terminal with time associated with such position information;storing base station data obtained from first base station, said base station data comprising first base station identification code (BS_id) and first base station position information (BS_pos);determining field test data from said received signal data (MT_data), positioning data (MT_data) and base station data (BS_id, BS_pos), such determined field test data comprising: an estimate of the angle (MT_BS_ang) between the first mobile terminal antenna orientation and the first base station antenna orientation,an estimate of the pathloss and the shadowing attenuation of the received signals (path_shad),at least one tap of the received signals (sig_taps), a tap being an information representing an estimate of phase and amplitude of a path of the multipath environment, andan estimate of the first mobile terminal speed (MT_speed)generating radio propagation characteristics of the multipath environment for simulation of radio propagation between the second base station and the second mobile terminal, using the determined field test data.展开▼
