该项目基于国家企业信用信息公示系统的反爬虫验证码类型,从数据采集、人工标注、模型构建、训练和验证的过程,最终构建形成demo演示
This project is based on the type of anti crawler verification code of the national enterprise credit information publicity system. From the process of data collection, manual annotation, model construction, training and verification, the final construction forms a demo demonstration (2023-11-10, Others, 0KB, 下载0次)
1请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能,并画出比特信噪比与误码率的关系曲线, 2在单径瑞利信道中
1. The theoretical bit error rate (BER) performance of BPSK coherent demodulation in single-path Rayleigh channel is derived, and the relationship between bit-to-noise ratio and bit error rate (BER) is drawn. (2) in single-path Rayleigh channel, the relationship between BER and BER is drawn. (2019-03-26, Others, 49KB, 下载0次)
