Java rabbitmq 消息发布测试程序
应用背景
参照官方代码写的消息发布测试程序,用于压力和性能测试。
TestBasicPublish.java 用于发布测试消息,参数代码内有描述 -? 可查看
TestBasicGet.java 用于单挑消息获取
TestBasicConsume.java 用于批量消息获取
关键技术
RabbitMQ 是信息传输的中间者。本质上,他从生产者(producers)接收消息,转发这些消息给消费者(consumers).换句话说,他能够按根据你指定的规则进行消息转发、缓冲、和持久化。
RabbitMQ 的一些常见的术语:
Producing意味着无非是发送。一个发送消息的程序是一个producer(生产者)。

dbpsk调制解调程序
SYMPCHUNK sets the number of symbols demodulated at once with a constant carrier frequency and symbol timing offset. This is a fundamental decoder parameter that establishes its carrier and symbol timing tracking bandwidth. Set it too low and the demodulator can"t accurately determine carrier frequency and symbol timing on a noisy signal. Set it too high and the demodulator may not be able to track large symbol rate offsets caused by Doppler shift and/or A/D or spacecraft clock errors. Or it might have trouble tracking high rates of change in the carrier frequency due to Doppler acceleration.The current value of SYMPCHUNK is 4*N1 = 512, where N1 = 128 is the order of the convolutional interleaver. 512 symbols is 512 milliseconds at 1000 symbols/sec, giving a frequency/time determination SNR that is 10*log10(512) = 27 dB greater than the Es/N0, not counti
