摘要： To assign a carrier frequency to different mobile stations in a conventional Space Division Multiple Access (SDMA) radio system, the stations are differentiated according to the direction in space from which they transmit radio signals to a base station. In addition, the distances between the base station and the mobile stations are compared. To prevent interference at the receiving site (base station BTS), according to the invention a carrier frequency (f) is assigned to the different mobile stations (MS1 to MS3) only if the directions in space (.THETA.1 to .THETA.3) are sufficiently different and the receive levels (P1 to P3) of the radio signals are sufficiently equal. To that end, each mobile station (MS1 to MS3) is assigned a guard area, which encompasses at least a preselected solid angle (lobe width w) and at most a preselected level space (dynamic range S). Any further mobile station wanting a radio link with the base station on the same carrier frequency (f) must be located in a permissible zone (Z) between the guard areas, which comprises a level range (zP) that is common to all preceding mobile stations. A further guard area is defined with each further connection, and the permissible zone (Z) is determined anew. The full capacity of the carrier frequency (f) is only attained when the permissible zone (Z) becomes so small that it no longer comprises sufficient space for the solid angle (w).

摘要： The determination of the direction of arrival of a radio signal by an antenna array connected to a base station of a radiocommunications system, particularly of an SDMA (Space Division Multiple Access) mobile radio system, is complicated by multipath. A method is known which uses the so-called ESPRIT algorithm and which is especially suited for a reliable estimation of direction, since the receive level (Sm) and the phase position (.phi.m) are measured for each radiating element and entered in a symmetrical matrix (A) in order to then determine the direction of arrival by eigenvalue decomposition.A simpler and faster method (100) is proposed which involves computing the eigenvector (Wn) corresponding to the dominant eigenvalue (.lambda.1) of this matrix (A), which indicates the direction of arrival (DOA) of the strongest radio signal (S) (steps 130 and 140). The computationally intensive eigenvalue decomposition is eliminated.

摘要： The invention refers to a mobile radio communication system (1) for downlink transmission and to a method for transmitting a signal (s) across at least two downlink paths (5, 6) of a multiple antenna (3, 4) mobile radio communication system (1). The system (1) comprises: a base station (2) comprising a plurality of antennas (3, 4); at least one mobile user equipment (8); at least two downlink paths (5, 6) across at least two of the antennas (3, 4) for transmitting a signal (s) from the base station (2) to the at least one user equipment (8), each downlink path (5, 6) comprising a complex channel coefficient (h1, h2); and a feedback path (9) for returning information on at least one complex weight (w) from the user equipment (8) to the base station (2), the at least one complex weight (w) being used for multiplying the signal (s) which is transmitted across at least two of the downlink paths (6). In order to enhance the tolerance of the system (1) against transmission errors (11) on the feedback path (9) it is suggested that the antennas (3, 4) of the base station (2) are disposed in such a distance (a) to one another that the channels of the antennas (3, 4) are correlated. It is further suggested that error detection mechanisms for detecting transmission errors (11) are incorporated in the feedback path (9). Further, it is suggested that error correction mechanisms for correcting transmission errors (11) are incorporated in the feedback path (9). Finally, it is suggested that filter mechanisms (19, 20) are incorporated in the user equipment (8) and in the base station (2).
