Abstract(in English) | We propose an atmospheric optical communication system using space-time block codes (STBC) without channel state information (CSI). In the proposed system, since binary pulse position modulation (BPPM) is used for the modulation scheme, the square-law combiner can be used at the receiver. Thus, the proposed system can be decoded without CSI. In addition the encoding procedure of the proposed system does not expand the signal constellation for nonbinary signaling. Thus, mapping and detection of the proposed system can be performed easily. We analyze the bit error rate (BER) of the proposed system in the presence of scintillation. We compare the proposed system to a single transmit aperture system (non-diversity) and the systems using Alamouti's STBC with coherent and differential detection. We show that although the BER of the proposed system is worse than those of the systems using Alamouti's STBC with coherent and differential detection, the proposed system can achieve the better BER than a single transmit aperture system in the presence of scintillation, without CSI and the expansion of the signal constellation. Note that the proposed system is easily applicable to other M-ary PPM schemes. |
