Abstract :
This paper proposes a new method for designing spread sequences for a spread spectrum (SS) communication and ranging system. The proposed sequence is a concatenated EOE sequence, which is composed of inner-sequences with EOE sequences and an outer sequence with an M sequence. We proposed EOE sequences that have equivalently good properties of both even and odd correlation, which are important for acquisition and demodulation in SS communications. Usually the concatenated sequences that PN-sequences are connected simply have bad properties of autocorrelation. Inner-sequences that composed the concatenated EOE sequence have good properties of correlation. Moreover the concatenated sequence has good properties of autocorrelation. This results in low peaks for autocorrelation of the concatenated EOE sequences, which is useful for achieving stable acquisition. And the proposal sequences have long period. So the concatenated EOE sequence is suitable for a spread spectrum communication and ranging system uniquely
