-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.
