This paper extends the operational Signal to Interference power Ratio (SIR) range of the blind adaptive arrays by subcarrier transmission power control (STPC) with selective utilization of maximum ratio combining (MRC) and power inversion adaptive array (PIAA). MRC strongly receives a desired signal in SIR>0dB while PIAA appropriately suppresses an interference signal in SIR<0dB. With the proposed method, MRC is applied to reception signals allocated higher power subcarriers and PIAA is applied to signals of lower power subcarriers. Computer simulation results show that the proposed method can suppress interference around SIR=0dB and improve operational SIR for the primary system to over 5dB, resulting spectral efficiency can be improved by 1.93-fold when 2 systems share the same frequency resource. |
