 The recommended method for compliance with Section 13 of the AGPLv3 license is
-to deliver a text message to each handset that attaches to the cellular

-"OsmoTRX AGPLv3" and a URL that can be used to access the OsmoBTS source code.  This

 message need not be delivered to handsets that are denied registration with the
 network, since those handsets have been denied service.

+In OpenBTS 2.6, such text messages can be delivered with the "Welcome Message"
+feature.  See the OpenBTS.config.example file for more information on the use of

- * between main thread feeding rate_ctr structures and the Rx/Tx threads
- * generating the events.
- * The idea is that upon read/write issues, lower layers (SDR APIs) provide us with

- * the stack through signal <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> with signal_cb
- * being a pointer to a "struct device_counters" structure, which contains
- * device (implementation agnostic) statful counters for different kind of
- * statistics.
- * That signal is processed here in device_sig_cb, where a copy of the "struct
- * device_counters" structure is held and the main thread is instructed through
- * a timerfd to update rate_ctr APIs against this copy. All this is done inside
- * a mutex to avoid different race conditions (between Rx andTx threads, and
- * between Rx/Tx and main thread). For the same reason, callers of signal
- * <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> (device_sig_cb), that is Rx/Tx threads,

+installation.
+
+One some systems (Ubuntu), you will need to define LIBS = -lpthread prior to
+running configure.
+
+To run OpenBTS, the following should be installed:
+
+	Asterisk (http://www.asterisk.org), running SIP on port 5060.
+
+	libosip2 (http://www.gnu.org/software/osip/)
+
+	libortp (http://freshmeat.net/projects/ortp/)
+
+	libusrp (http://gnuradio.org).
+	This is part of the GNURadio installation.
+	It is the only part used by OpenBTS.
+
+
+OpenBTS logs to syslogd as facility LOG_LOCAL7.  Please set your /etc/syslog.conf
+accordingly.

-About OsmoTRX
-=============
-
-OsmoTRX is a software-defined radio transceiver that implements the Layer 1
-physical layer of a BTS comprising the following 3GPP specifications:
-
-* TS 05.01 "Physical layer on the radio path"
-* TS 05.02 "Multiplexing and Multiple Access on the Radio Path"
-* TS 05.04 "Modulation"
-* TS 05.10 "Radio subsystem synchronization"
-
-OsmoTRX is originally based on the transceiver code from the
-[OpenBTS](https://osmocom.org/projects/osmobts/wiki/OpenBTS) project, but setup
-to operate independently with the purpose of using with non-OpenBTS software and
-projects, specifically within the Osmocom stack.  Used together with
-[OsmoBTS](https://osmocom.org/projects/osmobts/wiki) you can get a pretty
-standard GSM BTS with Abis interface as per the relevant 3GPP specifications.

+The Transceiver
+
+The transceiver consists of three modules:
+   --- transceiver
+   --- radioInterface
+   --- USRPDevice
+
+The USRPDevice module is basically a driver that reads/writes
+packets to a USRP with two RFX900 daughterboards, board 
+A is the Tx chain and board B is the Rx chain.  
+
+The radioInterface module is basically an interface b/w the
+transceiver and the USRP.   It operates the basestation clock
+based upon the sample count of received USRP samples.  Packets 
+from the USRP are queued and segmented into GSM bursts that are
+passed up to the transceiver; bursts from the transceiver are
+passed down to the USRP. 
+
+The transceiver basically operates "layer 0" of the GSM stack,
+performing the modulation, detection, and demodulation of GSM 
+bursts.  It communicates with the GSM stack via three UDP sockets,
+one socket for data, one for control messages, and one socket to
+pass clocking information.  The transceiver contains a priority
+queue to sort to-be-transmitted bursts, and a filler table to fill
+in timeslots that do not have bursts in the priority queue.  The
+transceiver tries to stay ahead of the basestation clock, adapting 
+its latency when underruns are reported by the radioInterface/USRP.
+Received bursts (from the radioInterface) pass through a simple 
+energy detector, a RACH or midamble correlator, and a DFE-based demodulator.
+
+NOTE: There's a SWLOOPBACK #define statement, where the USRP is replaced
+with a memory buffer.  In this mode, data written to the USRP is actually stored 
+in a buffer, and read commands to the USRP simply pull data from this buffer.
+This was very useful in early testing, and still may be useful in testing basic
+Transceiver and radioInterface functionality.

+At time n, start with a non-empty bag S of survivors from time n-1.
+Take a member out of S, and create all possible branches and their corresponding metrics.  If metric ratio is above T, discard branch.  Otherwise, check branch against entry in pruning table P.  If branch metric is smaller than the existing entry's metric in P, then replace entry with branch.  Otherwise, discard branch.
+Once all possible branches of S have been created and pruned, S should be empty.Empty pruning table back into S, thus P is now empty.  Repeat.
