Novel scheme for generating poly-phase sequence based on m-sequence

ZHONG Jie,CAI Fang,ZHAO Min-jian(Department of Information Science and Electronic Engineering,Zhejiang University,Hangzhou 310027,China)  
The training sequence with arbitrary length was demanded for good auto-correlation property and flat magnitude in frequency domain for synchronization and equalization in single carrier frequency domain equalization(SC-FDE) system.A novel scheme based on m-sequence,discrete Fourier transform(DFT) and inverse discrete Fourier transform(IDFT) was proposed to generate poly-phase sequence.The scheme remedied and expanded the sequence in frequency domain to get the sequence with demanded length,hence transformed it back into time domain to get the complex sequence.The complex sequence has good auto-correlation property,flat magnitude in frequency domain and short quantified bits,thus can be applied in SC-FDE system as both equalization training sequence and poly-phase spread spectrum sequence.
