1 This directory contains a work in progress service monitor for DECT
2 digital cordless phone base stations and handsets.
8 2007 Apr 27 - Converted to new hier_block2 format
9 2007 Apr 03 - Development on hold.
10 2007 Feb 11 - Added GMSK demodulation and option to log to file
11 2007 Feb 10 - Able to tune and log filtered baseband to file
17 usrp_dect.py - DECT receiver application
19 dect_receiver.py - Top-level hierarchical block (new type) implementing
22 usrp_source.py - Hierarchical block (new type) implementing a USRP
23 complex source, with convenience functions for tuning,
24 gain, decimation, etc.
26 gmsk2.py - Hierarchical block (new type) implementing GMSK
27 modulation and demodulation. This will eventually go

30 DECT Modulation Details
31 -----------------------
33 In the US, the FCC has allocated four carrier frequencies for DECT usage:
42 These are spaced at 1.728 MHz intervals.
44 The DECT PHY uses GMSK with a 0.5 bandwidth-time product at 1.152 Msym/sec,
45 for an occupied bandwidth (99% power) of 1.186 MHz (1.03 x symbol rate.)
