| Abstract(in English) | Adaptive array antenna signal processing with a blind algorithm is effective as a means to suppress co-channel interference without a priori information such as channel state information. Among them, the constant envelope algorithm (CMA) is known to exhibit strong interference suppression capability. It can be said that the array weight is derived using the fact that the probability distribution of the modulated signal has non-Gaussian nature. Focusing on the above point, we have proposed a time-domain symbol spreading to Gaussianize the property of interference signal. In OFDM, the signal of each subcarrier is distorted and the non-Gaussian property is destroyed by the asynchrony for FFT windowing. This paper introduces the interference suppression effect of the time-domain symbol spreading based blind adaptive array antenna, and consider its variation for a practical environment considering OFDM. |
