Cirpan Department of Electrical-Electronics Engineering Istanbul University Avcilar 34850 Istanbul Turkey Email hcirpan@ Traditional wireless technologies are confronted with new challenges in meeting the ubiquity and mobility requirements of cellular systems. Hostile channel characteristics and limited bandwidths in wireless applications provide key barriers that future generation systems must cope with. Advanced signal processing methods such as i the expectation-maximization EM algorithm ii the SAGE algorithm iii the Baum-Welch algorithm iv per-survivor processing v Kalman filters and their extensions vi hidden Markov modeling vii sequential Monte Carlo filters viii stochastic approximation algorithms in collaboration with inexpensive and rapid computing power provide a promising avenue for overcoming the limitations of current technologies. Applications of the advanced signal processing algorithms mentioned above include but are not limited to joint blind sequence detection decoding synchronization equalization as well as channel estimation techniques employed in advanced wireless communication systems such as OFDM OFDMA space-time-frequency coding MIMO CDMA and multiuser detection in time-and frequency-selective MIMO channels. In particular the development of suitable algorithms for wireless multipleaccess systems in nonstationary and interference-rich environments presents major challenges to the system designer. While .
