Abstract: Abstract The rapid development of wireless communications is not possible without advancement of the wireless transceiver technology. Regardless the wide area network (WAN) or local area network (LAN), wireless transceivers constitute the physical layer of any wireless network. Notwithstanding the hardware progress, algorithms for digital signal processing in wireless transceivers have also experienced major developments in the past two decades. Notables include those for MIMO wireless channels in order to increase the data rate and to satisfy the more stringent quality of service (QoS) requirements. This chapter focuses on signal processing side of the wireless transceiver technology, including channel estimation, equalization, precoding and data or symbol detection which are fundamental to design of wireless transceivers.In this chapter, several wireless systems will be introduced, with emphasis on direct sequence (DS) spread sequence CDMA (code division multiple access) systems and OFDM (orthogonal frequency division multiplex) modulated systems over fading channels. Optimal algorithms will be presented for zero-forcing channel equalization, precoding, and linear receivers. These algorithms are developed for MIMO channels due to the multiuser nature of the wireless communication system and multiple antenna technology. Finally optimal multiuser symbol detection will be considered jointly with decision feedback. It will be seen that Kalman filtering and LQR control play pivotal roles in developing optimal design algorithms for wireless transceivers.
