摘要： The invention relates to a cognitive SIMO network access method based on cooperative relay, wherein a cognitive base station collects channel responses in a network and judges whether the cognitive users can cooperate with a primary user to achieve the target transmission rate required by the primary user or not, if so, a cognitive SIMO network is accessible to a frequency band licensed to the primary user; otherwise, the cognitive SIMO network is non-accessible. The access method can enable a plurality of the cognitive users and the primary user to simultaneously use the same licensed spectrum in the same geographical position, on the premise of ensuring the target transmission rate of the primary user, and further improve the utilization efficiency of the spectrum as far as possible. As the access method is based on cooperative communication, the nearer the distance from the cognitive network to the primary network is, the greater the network throughput can be achieved; and furthermore, a large-range network coverage can be realized, so the deficiencies in the existing cognitive radio access ways are made up.

摘要： The invention relates to a resource distribution method for throughput maximization in a cooperative cognitive SIMO network. The primary user sends data after receiving a cooperation confirmation message, and the cognitive network keeps silence, receives the information data of the primary user and simultaneously decodes the data. The cognitive users which successfully decode the data utilize part of their transmission power to send the data of themselves to the cognitive base station, the remaining transmission power is used for helping in forwarding the data of the primary user; the cognitive users which cannot successfully decode the data only send the data of themselves and do not forward the data of the primary user. The cognitive base station eliminates the interference of the data of primary user in the received mixed signals and performs beamforming on the signals after eliminating the interference. According to the combined adjustment of the transmission power vector, the power distribution factor vector and the beamforming weight vectors of the cognitive SIMO network, the maximum throughput performance can be realized in the cognitive network while the target transmission rate of the primary user is ensured, furthermore, very fast convergence rate can be realized in the proposed resource distribution method.

摘要： An improved method of arc welding uses a single power supply connected to opposed welding torches placed on both sides of a workpiece. Each torch is connected to a different polarity lead of the power supply and forms a separate arc with the workpiece. When a current is supplied to the first torch, it is guided from the first electrode, through the first arc, the workpiece, the second arc, and to the electrode of the second torch. This guiding function improves the penetration, concentration, as well as the directional stability of the arc. This permits the effective and efficient welding of relatively thick workpieces using existing equipment at low current levels.
