Abstract (eng): | This thesis presents a black-space spectrum access scheme for overlay cognitive radio in TV band. Physical layer implementations of secondary systems using software defined radio technology have been proposed. We consider two types of secondary transmitters with WLAN-type and LTE-type frame structures in order to study the impact of secondary transmission over primary pilot carriers on performances of channel estimation and interference cancellation algorithms. Bit error rate has been used as performance metric, and performances of the two secondary systems have been presented in different scenarios. The effect of secondary transmitters interference power level on performances of primary and secondary receivers has been investigated. |
