CoGnitive radio network for the smart Grid
LX25 FPGA. e low-band tunable RF module can be configured
to have either 5- or 20-MHz bandwidth with working frequencies
of 200–1,050 MHz for the transmitter and 200–1,000 MHz for the
receiver. e nominal noise figure of this RF module is 5 dB. Other
frequency bands may be covered by several other RF modules.
ere are two favorable features of the SFF SDR DP for cognitive
radio networks. One is that a SFF SDR DP is in SFF and can be
moved easily. e other is that it is capable of supporting full-duplex
communications. However, there are also two technical drawbacks of
using it to build nodes for cogn ...
