Hi Ron and Marcus,For frequency higher than 6 Ghz, a down converter can be used to over come this problem.for the data rate and bandwidth, the PC i'm using has the following specifications:Architecture: x86_64CPU op-mode(s): 32-bit, 64-bitByte Order: Little EndianCPU(s): 20On-line CPU(s) list: 0-19Thread(s) per core: 2Core(s) per socket: 10Socket(s): 1NUMA node(s): 1Vendor ID: GenuineIntelCPU family: 6Model: 63Model name: Intel(R) Xeon(R) CPU E5-2660 v3 @ 2.60GHzStepping: 2CPU MHz: 1553.804CPU max MHz: 3300.0000CPU min MHz: 1200.0000BogoMIPS: 5197.32Virtualization: VT-xL1d cache: 32KL1i cache: 32KL2 cache: 256KL3 cache: 25600KNUMA node0 CPU(s): 0-19I think it can handle this rate. Please correct me if i'm Wrong.i have other questions:
- There are (synchronizers, equalizers, channel codes etc) blocks in the gr-dvbt project why I cant use them?
- when you mentioned channel coding do you mean that i need to create a new one? and Why would I need it?
- If i need BCH performance Why is difficult to achieve?
- if the data requirement is fine (CPU and etc), what is the best way to start building the receiver? How can I figure out the blocks That i need for this receiver?

2) Bandwidth range : 2 - 56 MHz
3) Modulation : Qpsk - 256 QAM
4) Data rate range : 150Mbit/s - 326Mbit/s.
5) Error correction method : i thinks it is FEC.IhabOn 22 August 2016 at 12:33, Ihab Zine <address@hidden> wrote:Hi All,I'm working on a project using GnuRadio And USRP 205 mini, i'm at the stage where i need to demodulate a microwave link signal.Anyone has an experience with Microwave link or tried to do something similar? Is it possiable to do it in gnuradio? or is there another approaches to do it?I'd appreciate any information you could give me.ThanksIhab
