In this paper, an experimental CSK circuit using Chua s circuit with the whole modulation and demodulation process under changeable communication channel gain is presented.
Blind equalization is one of the key technologies of blind demodulation to compensate the channel distortion.
盲均衡是实现信号盲解调的关键技术之一,是补偿信道失真的重要手段。
