2. The transmitter comprises a tunable laser (TL) operating at 1550 nm with 1 MHz linewidth, the part of PRBS generating 40 Gbit/s pseudorandom bit sequence (PRBS), and pulse generator generates NRZ-DPSK and RZ-DPSK pulse shape respectively, the optical carrier was modulated with a 40 ...
PULSE generatorsTRANSMITTERS (Communication)This paper presents a non-return-to-zero (NRZ)/4-level pulse amplitude modulation (PAM-4) dual-mode wireline transmitter with an eye-opening enhancement technique to improve horizontal eye-opening. With the eye-enhancement ...
我是用BER TEST SET生成伪随机码后使用MATLAB进行编码,编码后的码长比原码长要更长,但是将编码后的二进制序列传输给NRZ Pulse Generator后生成的非归零电信号的长度是编码前的长度,这就导致很多信息会被舍弃,这个在哪里设置可以更改呢 最左侧的图为编码前的二进制序列长度,中间的为编码后的二进制序列长度,最后的...
