Abstract

Using M-ary QAM and PSK, various modulation methods are researched so far. In this paper, a new constellation method of $4L^2$-PSK that normalized circular multi-layer method is proposed with the advantage of those modulation methods. These replacements of signal points complement weak points of an nonlinear radius increment as a layer increases in M-ary QAM and a low efficiency in PSK compared with QAM. But, $4L^2$-PSK have some problems that in the power efficiency and difference of BER in each layer, So in this paper suggest that advanced $4L^2$-PSK also.
