| Abstract(in English) | Future wireless networks will need to support users, be they persons or devices, having heterogeneous characteristics such as different symbol rates and modulation schemes. For this purpose, the development of techniques for rejecting any heterogeneous interference is deemed as an important issue. In this study we focus on interference rejection for users having different symbol rates. One candidate technique is cyclic Wiener filtering which has the potential to separate desired and interfering signals that share the same bandwidth but have different symbol rates. In a previous work, we have proposed a pulse shape design to enhance the cyclic Wiener filtering's rejection capability of in-band interference lying within the Nyquist bandwidth of the desired signal. However, the performance evaluations in this previous work were limited to additive white Gaussian noise (AWGN) channels with one receive antenna. In this paper, we further investigate the performance of cyclic Wiener filtering under frequency-flat and selective Rayleigh fading channels, and with one or two antennas at the receiver. Computer simulations are conducted to clarify the effectiveness of cyclic Wiener filtering using our previously proposed pulse shaping, under these channel conditions as well. |
