How can a spreading code be designed to produce a flat energy spectrum, ensuring uniform energy distribution across all frequencies?

Recently I've read a paper on Reed–Solomon Code, in the decoding part, the author proposed a modified RiBM algorithm which use t cycles(while RiBM algorithm needs 2t cycles) to find the error location ...

I'm trying to use scipy.signal.remez to design half-band filters. My understanding is that this targets an equi-ripple criteria to design the filter. What I am ...

I'm new to digital signal processing and would like to know how to make a QAM-M modem that generates proper passband signal and saves it as a WAV file. The tool should allow me to specify the carrier ...

In recent posts, Evaluating THD for any Test Tone and any Sample Rate, I have attempted to assess the audio quality of my Android device by using Oboe in Native C++, and evaluate THD in real time ...

Working on an air-sonar device and looking for a practical development sequence and DSP filtering strategy that can reliably identify and time the RX of a known TX short audio ping. Some research ...

I'm writing as a follow up to this: Evaluating THD+N in C++ on the Fly I am using C++ where FFT computation is restricted to time windows which are powers of 2. I am using KissFFT, because it was the ...

I am working on finding Fourier Transform for a signal given by $$ x(t) = \sum\limits_{n=-\infty}^{\infty} e^{\vert t-2n \vert} $$ I got a hint that this sign is periodic with period, $T = 2$. But to ...

I'm designing a Kalman filter for a navigation system. Unfortunately, some of my measurements are going to come in out of order. I know the best solution is to buffer the measurements and process them ...

I am trying to understand the output bandwidth of a Square Root Raised Cosine filter. I have these parameters in the system: The DAC sampling rate is 5GHz. The symbol rate is 2.5GHz so I have 2 ...

I've known for a while that it is important to use a double sided spectrum when performing an IFFT in order to ensure the recovered time domain signal is purely real. However I've also seen that using ...

In a one of the publications I encountered following statement: "The 3rd order PLL, while being more flexible in front of high dynamics, only remains stable for bandwidths below 18 Hz." ...

I’m getting advice from an LLM on this, but I’d like humans to weigh in. I have LFP data from two brain regions. It’s segmented many ways, listed from lowest to highest level: by uninterrupted ...

I’m implementing a 2D-OFDM radar (SISO) simulation based on the paper “Maximum Likelihood Speed and Distance Estimation for OFDM Radar” by Braun, Sturm and Jondral. The system transmits MPSK-modulated ...
