SDR File Reader Library

sdr_file_reader is a Rust library for reading and parsing Software Defined Radio (SDR) files. It supports a wide range of sample formats, including unsigned and signed 8-bit and 16-bit integers, as well as 32-bit and 64-bit floating-point numbers. The library provides an easy interface for converting raw SDR data into complex samples that can be used for further processing.

Features

• Supports multiple sample types: u8, i8, i16, u16, f32, and f64.
• Converts raw SDR data into complex samples (Complex<f32> or Complex<f64>).
• Efficient reading of SDR files in configurable chunks.

Installation

Add the following to your Cargo.toml:

[dependencies]
sdr_file_reader = "0.1.0"

Usage

Here is an example of how to use the sdr_file_reader library to read SDR data from a file:

use sdr_file_reader::{SdrFileReader, SampleType};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let file_path = "gqrx_20240929_015218_580206500_2400000_fc.raw";
    let mut reader = SdrFileReader::new(file_path, 1024, SampleType::F32)?;

    while let Some(samples) = reader.read_next_chunk_complexf32()? {
        // Process the samples here
        println!("Read {} samples", samples.len());
    }

    Ok(())
}

Sample Types

The SampleType enum represents the different formats of samples that can be used in SDR files:

• U8: Unsigned 8-bit integer
• I8: Signed 8-bit integer
• I16: Signed 16-bit integer
• U16: Unsigned 16-bit integer
• F32: 32-bit floating point
• F64: 64-bit floating point
