METHODS AND DEVICES FOR CSK COMMUNICATION, CSK TRANSMISSION, AND CSK RECEPTION

摘要

PURPOSE:To prevent demodulation error of data by comparing two correlation outputs on a reception side and assigning 0 or 1 of received data according to the comparison result. CONSTITUTION:A Manchester code M sequence which is generated by one Manchester M sequence generator 31 is set in one correlator 21 and the correlation between the set sequence and a received signal RXI is found; and a Manchester code M sequence which is generated by the other Manchester M sequence generator 32 is set in the other correlator 22 and the correlation between the set sequence and received signal RXI is found. Then, when the correlation output of the correlator 21 indicates a larger correlation peak value than the correlator 22, reception data of 0 is generated, but when the output of the correlator 22 indicates a larger correlation peak value, received data of 1 is generated. Consequently, the demodulation error of the data is eliminated.
