relay

  认知中继网络包括一个主用户发射机和接收机，一个次用户发射机和接收机，以及一个放大转发中继。次用户发射机和中继从自然界获取能量。次用户共享主用户的频带进行数据传送，中继放大转发主用户发射机和次用户发射机的信号。次用户发射机和中继根据获取的能量和数据传送要求控制发射功率。功率控制建模为在能量因果约束、(Cognitive relay network includes a primary user transmitter and receiver, a secondary user transmitter and receiver, as well as an amplify and forward relay. Secondary user transmitter and relay obtain energy nature. Secondary users share a frequency band of the primary user data transmission, the relay amplification repeater primary user and a secondary user transmitter the transmitter signal. Secondary user transmitter and a relay and a data transfer request according to the energy obtained by controlling the transmission power. The power control is modeled as a causal constraints in energy,)
