hi all: I found there is a program (pick_bitrate.py) about bit-rate in the /gnuradio-example/python/digital/ .And there is one quertion confuse me about this program. There is a formula about bit-rate in the program such as bitrate = converter_rate / interp / samples_per_symbol. I know the converter_rate is 128Msam/s,so if I set the interp and samples_per_symbol, I can get the bit-rate.and is it the same as in the GRC? In the grc, I can set the samples_per_symnol in the flow graph and the interp in the usrp_sink.so can I calculate the bitrate through the formula in the pick_rate.py? Besides,I found there is default bit-rate value in the benchmark_tx.py.so is that mean I can set the bit-rate through two ways,one is said above,the other is diretcly set the bit-rate in the program's (benchmark_tx.py -r) option? and in the second way, the interp is calculated by the formula.Am I correct? thank you! 搜索本应是彩色的,快来体验新一代搜索引擎-必应,精美图片每天换哦! 立即试用! |
