| Abstract(in English) | Co-channel interference is a major deteriorating factor limiting the capacity of cellular radio systems. To resolve this, Trellis-Coded Co-channel interference Canceler(TCC) has been proposed. In TCC the Trellis-Coded Modulation(TCM) is introduced to both the desired signal and the interference signal which enhances the canceling performance. Since the received signal of TCC can be considered as being encoded and modulated by a single equivalent TCM scheme, the performance of TCC can be evaluated by investigating the equivalent TCM. In our work an asymptotic estimate(AE) and an upper bound of BER are calculated to evaluate the performance of TCC in static channel. In the evaluation of AE, the squared Euclidean distance(SED) between sequences is shown to be following the shape of sin(.) function, which explains clearly BER performance graph against the phase difference φ. The upper bound is calculated using a transfer function based on the matrix representation. For TCC with trellis-coded QPSK at all transmitters, the results of AE BER and upper bound are compared with that of the computer simulations. |
