Wireless sensor networks (WSNs) have captured considerable attention recently due to their enormous potential applications. Energy has become the bottle-neck problem and has constrained WSNs widely applications. Cluster mechanism has been widely pursued by the research community in order to prolong the life of WSNs. In this paper, we propose an(More)
Today, high speed broadband wireless access has become a hotspot of research and application, LTE is a representative of it, and MIMO is one of key technologies of LTE. However, the MIMO signal detecting algorithms are indispensable process in LTE system design. In this paper, we analyze the architecture of LTE MIMO receiver according to 3GPP LTE draft,(More)
Channel estimation problems in theoretical as well as applied statistics have long been of great research interest given their importance in MIMO-OFDM systems based on IEEE802.16e, DOA estimation plays an major role in the channel estimation. In this paper, we discuss principles of MMO-OFDM channel models, summarize classical DOA estimation algorithms,(More)
