| 摘要 |
The invention concerns a device for pro-active estimation of interference signal ratio in a cellular radiocommunication network terminal using in transmission primary frequencies and secondary frequencies whereof the re-use rate is higher than that of the primary frequencies. The device knows the level received by said terminal of a station line cell (A1) to which it is connected, it is also provided with the levels received (LB2, LC3, LD2, LE1, LG2, LF1) by said terminal from neighbouring cells (B2, C3, D2, E1, G2, F1), it selects a reference cell (B2) among the station line cell and the neighbouring cells, it produces a potential noise by summing (N1) the received levels (LD2, LG2) of the cells (D2,G2) using the same secondary frequencies as the reference cell (B2), it feeds this estimation into the reference cell (B2) by dividing the level received from said reference cell by the potential noise.
