Example Usage

• file

import rpps as rp

mod = rp.mod.load("QPSK")
mod.set_mapping(mod.get_maps()[0])
ecc = rp.coding.load("blk", "hamming.7_4")
scr = rp.scram.load("fdt", "v35")

enc_msg = rp.dobject.StreamData(b"Hello World!")

f_pipe = lambda inp:inp * scr * ecc * mod
r_pipe = lambda syms:syms / mod / ecc / scr

syms = f_pipe(enc_msg) # Encode data with ecc, and mod. Get the symbols

data = r_pipe(syms) # Read the symbols

dec_msg = rp.dobject.StreamData(data)
print(f"{enc_msg.hex == dec_msg.hex}") # Check decoded data is what you encoded

Real-time spectrum

• file

import rpps as rp

sink = rp.serial.File(<format>, <path>)
meta = rp.Meta(Fs=<>, cf=<>)
sweep_time, display = 10, 50 # ms
num_samps = int((sweep_time/1000)*meta.Fs)
nfft, overlap, vbw = 1024, 0.8, 1000
window = "blackman"
fig, ax = plt.subplots()
im = ax
for samps in sink(num_samps):
    snips = rp.utils.stft.stft(samps, nfft, overlap, window)
    psds = rp.utils.stft.psd(snips, meta.Fs, vbw)
    im = rp.viz.rt.Persistent(im, psds)
    plt.pause(display/1000)

Install

1. Run python3 -m pip install rpps
