BACKGROUND Widely used restriction-dependent cloning methods are labour-intensive and time-consuming, while several types of ligase-independent cloning approaches have inherent limitations. A rapid and reliable method of cloning native DNA sequences into desired plasmids are highly desired. RESULTS This paper introduces ABI-REC, a novel strategy combining(More)
In OFDM-based spectrum sharing networks, due to inefficient coordination or imperfect spectrum sensing, the signals from femtocells or secondary users appear as interference in a subset of subcarriers of the primary systems. Together with the inter-carrier interference (ICI) introduced by high mobility, equalizing one subcarrier now depends not only on(More)
Non-orthogonal multiple access (NOMA) is a promising technology in future mobile communications. In this letter, we study the channel estimation and power allocation problem for the two-user NOMA downlink system with one strong user and one weak user. Firstly, we introduce a new type of linear estimator that aims at maximizing the average effective(More)
In this paper, equalization of multihop relaying orthogonal frequency division multiplexing (OFDM) signal is investigated under time-varying channel with unknown noise powers, channel orders and Doppler frequencies. An iterative algorithm is developed under variational expectation maximization (EM) framework. The proposed algorithm iteratively estimates the(More)
