PROBLEM TO BE SOLVED: To provide an improved signal detection method in a TDMA mobile system with co-channel interference. SOLUTION: Primary signal r<SB>1</SB>and at least one interfering co-channel signal r<SB>2</SB>... r<SB>N</SB>are received through the same TDMA channel F<SB>1</SB>, T<SB>S3</SB>. The co-channel signals propagate through multipath channels h<SB>L.1</SB>... h<SB>L.N</SB>independently of each other, and are provided with a unique wave form coding. In addition, the co-channel signals have different but known training sequences. In the invention, the multipath channel estimates of the primary signal r<SB>1</SB>and at least one interfering co-channel signal r<SB>2</SB>... r<SB>N</SB>are determined through the received training sequences. After that, the primary signal is detected by utilizing the transmission channel estimates of both the primary signal and at least one interfering co-channel signal. COPYRIGHT: (C)2008,JPO&INPIT
