First, a new geometrical theory is presented for channel depolarization in UHF fixed-to-mobile (F2M) and, mobile-to-mobile (M2M) channels. This new geometric approach reveals the geometric origin of channel depolarization and provides a means for computing cross-polarization discrimination (XPD). Afterwards, new methods are considered for exploiting polarization in cellular systems. The first method considers a precoding-assisted dual-polarized multi-cell MIMO system, which is an extension of uni-polarized multi-cell MIMO. Our singular value decomposition (SVD) precoded-aided approach is shown to outperform the conventional MMSE multiuser detector in terms of symbol error rate in a dual-polarized multi-cell MIMO downlink scenario over flat fading channels. The second method considers a novel cellular down-link Polarization Division Multiple Access (PDMA) scheme with collaborative transmitter-receiver-polarization adjustment and polarization filtering detection. The fundamental novelty of the proposed scheme is the adjustment of transmit polarization angle to yield a more desirable complex cross-polarization discrimination (XPD) observed at the receivers, thus, allowing the multiplexed streams to be extracted more effectively. The scheme is applied to an LTE-like multi-carrier air interface operating on frequency-selective channels. 该讲座为北京邮电大学60周年校庆系列讲座之一，可盖章，欢迎全校师生踊跃参加。校学术委员会电子工程学院 2015年4月16日主讲人简介.docx http://portal.bupt.edu.cn//html/main/col51/2015-04/21/20150421093315530403966_1.html
