Data-Efficient Blind OFDM Channel Estimation Using Receiver Diversity

Overview This paper investigates non data-aided channel estimation for cyclically prefixed orthogonal frequency division multiplexing (OFDM) systems. By exploiting channel diversity using only two receive antennas, a blind deterministic algorithm is proposed. Identifiability conditions are derived that guarantee the perfect channel retrieval in the absence of noise. In the presence of noise, the proposed method has the desired property of being data efficient - only a single OFDM block is needed to achieve good estimation performance for a wide range of SNR values.
