Stabilized Interference Suppression by Initial Antenna Selection for CMA/MMA Adaptive Array over Fading Channel

Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes an initial antenna selection for constant modulus-based blind interference suppression algorithms to stabilize their prominent interference suppression performance. Constant modulus algorithm (CMA) is well known blind adaptive array scheme, but it cannot suppress the interference when signal-to-interference power ratio (SIR) is smaller than 0 dB. It faces strong limits on their applicable region over Rayleigh fading channels where instantaneous channel gain fluctuates over 10 dB range. Even if the expected desired signal strength is larger than interference, CMA may still miscapture the interference and incorrectly suppress the desired signal. Our proposal is simplified approach to select the antenna element whose reception power is maximal. Certain antenna element can be expected to capture the desired signal precisely under the condition where SIR is statistically positive, so that the CMA processor can utilize it as an initial input. This condition will be ensured by increasing antenna element number, supported by the trends that base station antenna elements are going massive. This paper also verified applicability for multi modulus algorithm (MMA) to accommodate M-ary QAM use.
