Abstract
Based on the idea of no hit zone NHZ in frequency hopping FH systems new sequences with three no hit zones TNHZ in timefrequency hopping TFH systems are presented With the TNHZ in the time frequency TF correlation functions the proposed TNHZ sequences can be directly employed in timefrequency hopping code division multiple access TFHCDMA communication systems to reduce or eliminate multipath interference Simulation results show that TNHZ sequences can achieve much better bit error performance than the NHZ sequences and the traditional FH sequences
