PCT No. PCT/FI95/00551 Sec. 371 Date Apr. 7, 1997 Sec. 102(e) Date Apr. 7, 1997 PCT Filed Oct. 5, 1995 PCT Pub. No. WO96/11533 PCT Pub. Date Apr. 18, 1996A signal detection method in a TDMA mobile system with co-channel interference and receivers implementing the method. In the method, a primary signal (r1) and at least one interfering co-channel signal (r2-rN) are received on the same TDMA channel (F1, TS3). The co-channel signals propagate through multipath channels (hL,1 . . . hL,N) independent of one another, which provide them with a unique wave form coding. In addition, the co-channel signals have different but known training sequences. The multipath channel estimates of the primary signal (r1) and the at least one interfering co-channel signal (r2-rN) are determined through the received training sequences. After this, the primary signal is detected by utilizing the transmission channel estimates of both the primary signal and the at least one interfering co-channel signal. |
