Hello, I am currently in a capstone project group with the goal of using DPD to linearize signals through a GaN PA. We are using the LimeSDR-USB along with GNURadio to generate a signal.
This looks like excellent work, and we would like to try it out on our LimeSDR. However, we are having trouble flashing the Cypress FX3 firmware and programming the FPGA of the LimeSDR-USB, because the project was done using the PCIe variant.
Any help or advice in getting this to work on the LimeSDR-USB would be much appreciated. Thank you!
Hi Andrew, I have the same question. Is there any way we implement ADPD on LimeSDR-USB? I am aware that it has been implemented on QPCIe type and needs two LMS7002M ICs, and high speed FPGA. We will be using for Tetra amplifiers , relatively narrowband signal, low data rate apps. Cost of the QPCIe is a bottleneck.
QPCIe is now discontinued also. At the present time LimeADPD is only supported with LimeSDR X3, which unfortunately is not cheap. We may at some point in the future look at whether we could add support for low cost boards, but this is not a priority, as the main use case is high performance, wideband systems.
