Multiantenna wireless systems have shown great promise in achieving high rates. We consider an OFDM multiple transmit/receive antenna system. We propose a linear non-redundant block pre-coding scheme, that is applied at the input of the OFDM system. The coding spreads the symbols of each user over all subcarriers, thus increasing multipath diversity, and at(More)

—This paper investigates a combined macro and femtocell communications deployment where macro users suffer significant downlink interference from femtocells. Based upon the large-scale cellular network model using stochastic geometry , we analyze the performance of the asynchronous ABSF configuration, where femtocell independently reserves resource for the(More)
Device-to-Device (D2D) communication has advantages of improving the spectral resource efficiency. But unfortunately, it brings about interference and potential secrecy hazard. In this paper, a Stackelberg game based power control algorithm is provided to enhance the physical layer security underlaying D2D communication by utilizing the interference. Then,(More)
Asthma is a common chronic inflammatory disease in the airways with wide prevalence, and it is thought to be caused by the combinational factors in environment and genetics. A large body of studies has suggested that cell immunity played a vital role in regulating the airway hyperreactivity (AHR) and inflammation. Therefore, we here developed a mouse model(More)
