Abstract

A novel family of frequency hopping sequences based on iterated block cipher is proposed for frequency-hopping multiple-access (FHMA) communications.The design offers a class of nonlinear FH codes with high security

large linear span and a uniform spread over the entire frequency bandwidth.Moreover

FH sequences among the family are independent from each other and they perform as well as random patterns in terms of multiple access interference in anti-jamming applications.With the performance of packet error and throughput for FHMA network being derived in theory

numerical results of the 3DES sequences are presented

comparing with those of shift register sequences and chaotic FH sequences.Efficiently implemented in field-programmable-gate- arrays (FPGA)

the generator prototype of the proposed sequence has been realized and incorporated into fast FH radio.
