We propose a new radio resource management algorithm which aims at minimizing the base station supply power consumption for multiuser MIMO-OFDM. Given a base station power model, that establishes a relation between the RF transmit power and the supply power consumption, the algorithm optimizes the trade-off between three basic power-saving mechanisms:(More)
The anti-inflammatory cytokines interleukin-10 (IL-10) and interleukin-13 (IL-13) were shown to reduce hyperalgesia in some models such as rats exposed to UV rays. In addition, IL-10 was also shown to reduce hyperalgesia in high dose of Leishmania major-induced inflammation in BALB/c mice accompanied by a significant decrease in the levels of interleukin-1β(More)
A novel interference alignment (IA) algorithm is presented. Interference alignment solutions can be obtained in closed-form for special cases only. In general, iterative algorithms need to be used. Most of these algorithms are based on a joint design of precoders at the transmitter side and receive filters at the receiver side, while the proposed method(More)
In this paper, analytical rate expressions of interference alignment (IA) algorithms applied to the multiple-input multiple-output interference channel are derived in the large system limit. A large system analysis is performed by fixing the number of users and letting the number of transmit and receive antennas go to infinity at a finite fixed ratio. The(More)
BACKGROUND Gap-junctional intercellular communication (GJIC) is implicated in physicological processes and it is vitally important for granulosa cell (GC) differentiation and oocyte growth. We investigated the expression of connexin 43 (Cx43), a gap junctional protein, in normal and androstenedione-induced polycystic ovary (PCO), the effects of(More)
A new iterative method based on cooperative precoding for the two-user multiple-input single-output (MISO) interference channel (IC) is proposed. In contrast to existing methods, precoders are designed in order to maximize a lower bound of the sum rate. Useful and interference powers are exchanged between the transmitters at each iteration. Numerical(More)
The predominantly used channel reciprocity condition in time-division-duplex mode only holds in practical systems if the transmit and receive hardware chains at the base station (BS) and at the user equipments are perfectly calibrated. Otherwise, there is a mismatch between the uplink (UL) and downlink channel state information (CSI) that leads to(More)
