Abstract :
Based on the idea of no hit zone (NHZ) in frequency hopping (FH) system, new sequences with three no hit zones (T-NHZ) in time-frequency hopping (TFH) systems are presented. With the correlation functions of the T-NHZ in the time-frequency (TF), the proposed T-NHZ sequences can be directly employed in time-frequency hopping code division multiple access (TFH-CDMA) communication systems to reduce or eliminate multipath interference.
