Re: GSoC'21 - View Only Mode

Thanks for posting these updates. Here are a few questions, maybe you already have plans for these. The user might want to disable saving of evaluated params for size, security, etc. Would saving be optional? Some evaluated expressions could be huge, filter taps for instance, and can be readily r

Software Defined Radio Programme ready

Dear lists, the Software Defined Radio Academy 2021 is going to take place next weekend, in one week's time, on Saturday June 26 and Sunday June 27. I'd also like to take the opportunity to point your attention to the European GnURadio Days which start slightly before, and overlap with the SDRA

Re: How to remove channel noise?

Hi, besides the hint to work through textbooks, I'd like to point out that you will probably have more success if you start with nearly perfect "Channel Model" coefficients and then observe changes in the following order: 1. Noise Voltage: 0 (and raise it slowly e.g. in 1e-2 increments. 2. Ta

Re: How to remove channel noise?

Hello 能书能言, You can take multiple samples and average out the noise (if the transmitted signal is not varying quickly), but you need to obtain channel estimates in order to recover the original phase and amplitude. You will have to transmit additional signals (known by the receiver) and use the
