Thanks for the video. I imagine Q channel is delayed by half symbol time BEFORE the shaping filter. Is it possible to implement that delay AFTER shaping filter as it is easier in hardware.

Yes, it is possible

You’re right about the filter ringing being a cause of high amplitude transients. Applying the delay after the shaping filter can help with implementation simplicity in hardware, but it doesn’t fully address the transient issues caused by the filter. This is because the filter applies its response without being aware of the symbol timing offset between the I and Q channels, which can lead to residual ringing. When you place the delay before the shaping filter, the filter can smooth the transitions more evenly across the I and Q paths, reducing the high-frequency transients and preventing them from getting amplified by subsequent stages like upsampling filters before the DAC. Delaying after the filter helps, but it’s more of a partial solution, and the more upsampling you have, the more noticeable the transients might become. So, while delaying after the filter is easier in hardware, the best signal quality comes from applying the delay before the shaping filter to reduce ringing at the source. This course researcherstore.com/courses/rf-communication-system-design/ will be of a great help for you in RF radio design.

@@Wislabi Well actually I deleted my previous comment but thanks. My conclusion is that Q offset is irrelevant until mixer stage as each I or Q channels are independent. Filter ringing will be part of filter response and will be same if there Q offset or not. So my final conclusion is that Q offset only makes sense when the channels are mixed and can be applied anywhere before mixer.

Where can AmBC systems be applied currently or in the future? What is the communication range in meters? How does the actual modification of the RF source signal occur? Is there a need for channel estimation in such systems? I would be grateful for a quick reply as I am preparing for a presentation on the topic

Hi Sir, thanks for the video. I want to ask you about srsRAN on ubuntu system. Firstly, I downloaded 22.04 version for ubuntu which is found in necessity section for srsRAN already. Then, I downloaded srsRAN but I'm not able to simulate it. Also, I have no idea how I should execute a examples to simulate? Could you help me about the topic? Thanks in advance
