Hi!
I want to implement an audio transmission system. As a reference i use 802.11g,
but my design is much simpler because my goal is 1.4 Mbps throughput (excl. all
overheads). I am using USPR + RFX2400. My goal is to implement as much as
possible on hardware. At the moment I am thinking about how to implement the
channel hopping (i plan to have 16 channels), and I can't find much detailed
information about how multiple-channel systems usually work. Do i need a
separate external oscillator (something like Chrystal) or can I generate all
the clocks I need on FPGA? As I understand, the same upsampling/downsampling
hardware is used, and the channel frequency is specified by small frequency
difference at the baseband, is it correct? If you know any good source where I
can read about multiple channel systems in detail - link will be appreciated!
Thank you for your answer!
Andrey
