Abstract: In this paper a method of generating 2k pseudo-random sequences to obtain stable long period of m-sequences and high complexity of chaotic sequences is discussed. A quasi-chaotic function acts as Mealy limited state machine and m-sequence acts as its input. The periodic nature of sequences is analyzed and the randomness of sequences is tested. The simulation results in chip of FPGA for frequency hopping code generator are reported. -
