在短波跳频通信中OFDM与Turbo码技术的研究-In the short-wave frequency-hopping communication OFDM with Turbo Code technology

A noncoherent, bandwidth-efficient modulation scheme is proposed for frequency-hopping multiple-access (FH-MA) networks. The proposed scheme is a combination of noncoherent -ary amplitude-shift keying (NMASK) and orthogonal frequency-division
