he mpdecoder project provides an MATLAB class mpdecoder that allows doing message passing (MP) decoding of binary LDPC codes. The MATLAB class mpdecoder actually calls the C++ class MPDecoder through the MATLAB MEX interface, which ensures its high decoding speed.

说明：  任务：设计一个4×2.5Gbit/s 长距离光纤传输系统，并利用OptiSystem 仿真验证。 要求： 1．采用波分复用技术，波长设置以100GHz 为间隔，频率分别为193.1THz、193.2THz、193.3THz、193.4THz，每个波长传输速率为2.5Gbit/s（NRZ），传输距离为300km。采用常规光纤，光纤损耗系数为0.25dB/km。 2．单通道光发送机最大输出功率为0dBm，光接收机的接收光功率不低于－26dBm，过载点为－10dBm。 3．可以采用EDFA 作为线路放大器，其中EDFA 的输入功率限制在－18～2dBm，最大输出功率20dBm，增益范围为13～25dB，噪声指数4.0dB。(Task: Design a 4 x 2.5 Gbit/s long-distance optical fiber transmission system, and use OptiSystem simulation to verify. Requirement: 1. Using wavelength division multiplexing technology, the wavelength is set at 100GHz intervals, with frequencies of 193.1 THz, 193.2 THz, 193.3 THz and 193.4 THz, respectively.
