Blind equalization and its application to the PACS system
Yue Chen, J.C.-Z. Chuang · 2002
High speed data transmission has become an important issue in mobile wireless communications. However, multipath propagation in wireless channels causes dispersion of the transmitted signals. We present a strategy to equalize the short burst without using a training sequence. This method is suitable for low-overhead TDMA systems such as PACS whose frame is very short. Different kinds of blind equalization algorithms are discussed and the simulation results indicate that the proposed method is feasible. We present the system model including the PACS system parameters and frame structure, and propose methods to equalize the radio channels using short sequences.
