That port contains signals that can be useful for debugging (fixing problems with the code). Currently it outputs the states of the axi_dma_master's state machines. Normally it would be disconnected, but if you were trying to understand a problem with that code then looking at the signals on that p

https://www.mathworks.com/help/lte/ug/channel-estimation.html Really the radio is part of the channel, so estimation algorithms I would think would be hardware agnostic. You might do better asking on a MatLab forum rather than here. Sent from my iPhone > On Feb 27, 2022, at 7:08 AM, Sadiq Iq

[USRP-users] How to estimate wireless channel using Matlab and ni USRP 2920

2022-02-27 Thread Sadiq Iqbal
Hi everyone, I am using matlab 2019 and NI USRP 2920 to implement a wireless network which consists of two Txs and two Rxs. I am using the general QPSK code which is available on the matlab website. But the thing is I can not find the channel estimation required when using a USRP. Therefore, can a

I am reading RFNOC replay block, end of the Verilog code I faced a debug code ... what's mean debug? what does it do? axi_dma_master #( .AWIDTH (MEM_ADDR_W), .DWIDTH (MEM_DATA_W) ) axi_dma_master_i ( // // AXI4 Memory Mapped Interface to DRAM // .aclk (mem_clk), .areset (mem_rst), // Write contro
