[Discuss-gnuradio] A interface between UHD source code function send() and benchmark?

2012-03-30 Thread baobaonanpo D
Hi, Is there anyone who use the uhd source code like tx_burst.cpp, use the function send(buffs, samples_to_send, md, timeout) to send data, I use the tx_burst.cpp and rx_samples_to_file.cpp to transmit and receive data, but the received data is without rules. I think the data must be deal with

[Discuss-gnuradio] Customized packet sink

2012-03-30 Thread anay tuljapurkar
Hey All, Is the gr_packet_sink.cc capable of handling a customized packet format structure or would one have to come up with a customized packet sink structure of ones own ignoring the complexity of access code/ sync vector ? Thanks, Anay. ___ Discu

Re: [Discuss-gnuradio] Pack k bits?

2012-03-30 Thread Nowlan, Sean
Any comment on this? I think the current implementation of gr_packed_to_unpacked_bb(int k, gr_endianness_t endianness) puts bits in an incorrect order when k > 1 and endianness = gr.GR_LSB_FIRST. From: discuss-gnuradio-bounces+sean.nowlan=gtri.gatech@gnu.org [mailto:discuss-gnuradio-bounces

[Discuss-gnuradio] gr-Trellis FSM

2012-03-30 Thread valentac
I've implemented a Manchester Decoder via an FSM using the combined Viterbi algorithm in gr-trellis, and its working great decoding my signal. However, I've noticed that after ~1000 times running (see code), I get an error... what(): fsm::fsm(const char *name): file open error I'd expect this to

[Discuss-gnuradio] gr_sync_block question

2012-03-30 Thread Nowlan, Sean
Do objects that extend gr_sync_block *require* that their work function *always* returns as many items as the scheduler asked in noutput_items, except for the case when a block may be completely finished producing items? What does the scheduler do if the (number of items returned) < noutput_item
