* Added support for modulation/demodulation of a generic constellation.Ben Reynwar2010-12-091-0/+64
| | | | | Not yet robust enough. Inefficient QAM modulation/demodulation also added (via the generic implementation).
* Added a new example python script (a stripped down version of ↵Ben Reynwar2010-12-031-0/+64

Defend against a peer that sends an invalid message length. Move initialization of select timeout Correct update of d_temp_offset (parallel construction) Identify memory leaks that occur on error conditions Use -1 as file descriptor "not open" value instead of 0 Add additional conditionalization of networking includes Flush pending errors in gr_udp_sink on disconnect() Rework UDP source and sink, with incompatible API changes Updates to udp source/sink (select(), wait, cleanup) Discard data in gr_udp_sink until receiver is started. Use getaddrinfo in gr_udp_{source,sink} Changes to gr_udp_{source,sink} for MinGW Ignore ENOPROTOOPT return from setsockopt(SO_LINGER)
| * | Rework UDP source and sink, with incompatible API changesDon Ward2010-05-046-52/+69
| | | | | | | | | | | | | | | | | | | | | | | | Remove source address specifications for sink; add connect() and disconnect() to sink; add get_port() to source; add optional EOF signaling (using zero-length packets) to sink and source; modify dial_tone, vector, and audio examples to match new code; add qa test case.
| * | Updates to udp source/sink (select(), wait, cleanup)Don Ward2010-04-301-3/+6
| |/ | | | | | | | | | | | | | | | | | | | | | | Use select() to avoid blocking on recv() in gr_udp_source (only known way to avoid blocking on Cygwin). Add wait argument to gr_udp_source to allow waiting for connection or accepting lack of connection as EOF; add --no-wait option to dial_tone_sink.py. Remove system dependencies from .h files; remove unused data members and (useless?) public open and close functions.
