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： 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.
摘要翻译：本发明涉及一种基于协同中继的认知SIMO网络接入方法，其中认知基站收集网络中的信道响应，并判断认知用户是否可以与主用户协作以实现主用户所要求的目标传输速率，如果是这样，则认证SIMO网络可以被许可给主用户的频带访问; 否则，认知SIMO网络是不可访问的。在确保主用户的目标传输速率的前提下，访问方法可以使多个认知用户和主用户在相同地理位置同时使用相同的许可频谱，并进一步提高主用户的使用效率频谱尽可能。由于接入方式是基于协作通信，距离认知网络到主网络的距离越近，网络吞吐量越大; 此外，可以实现大范围的网络覆盖，从而弥补了现有的认知无线电接入方式的缺陷。
