We propose a novel orthogonal modulation scheme-amplitude shift keying with frequency shift keying labeling for optical label switching. The ASK payload and FSK label are simultaneously generated by adoi:10.1007/s11082-017-1097-1Liu YangNational Engineering Laboratory for Next Generation Internet Access...
FPGA Modulation ASK FSK 1. Introduction Digital modulation is very important in our modern world as all digital electronics and transmission depends on it [1]. Modulation is a process when we send or mix low frequency signal with high frequency carrier signal. Basic sinusoidal signal can be defi...
There are three major classes of digital modulation techniques used for transmission of digitally represented data: Amplitude-shift keying (ASK) Frequency-shift keying (FSK) Phase-shift keying (PSK) key应该是这个意思:roughen a surface so that plaster or paint will stick to it, 把表面弄粗糙以便...

The ASK payload and FSK label are simultaneously generated by a dual-parallel Mach–Zehnder modulator. The ASK payload is encoded by Manchester coding, in order to minimize the impact of “0” payload signal on the whole system performance. The transmission performance of the modulation scheme is...
1、仿真实现ask、psk、fsk、dpsk、qam技术一数字调制系统的相关原理数字调制可以分为二进制调制和多进制调制,多进制调制是二进制调制的推广,所以本文主要讨论二进制的调制与解调,最后简单讨论一下多进制调制中的mfsk(m元移频键控)和mpsk(m元移相键控)。最常见的二进制数字调制方式有二进制振幅键控(2-ask)、移频...
