if estimation signals are opposite phase to reference signals, the si-snr still decrease. But for communication signals(such as QPSK、BPSK), the opposite phase causes the bit error rate almost 1. How t…

I am evaluating this library to see if it can be used to perform the 5G NR LDPC decoding. However, I am struggling to get it configured.
I can build and run the factory example at https://github.c…

For some reason, the frequency used for an uplink and downlink is not the same. The uplink consumes the expected amount of bandwidth (1 bit/Hz for BPSK with no encoder), but the downlink only consumes…

Hello @osqzss ,
I've recently been introduced to the wonderful world of GNSS and the gps-sdr-sim works perfectly for simulating GPS L1 signals.
I would really love to contribute to this repo and…

Hi Adrian,
just wondering if someone tested reception of SARSAT BPSK 400 text
in direct (406 MHz) or relay mode (1540 MHz)?
Can existing presets in qradiolink SW allow BPSK 400 setting ?

Hi,
in experiments with different PHY modes of the AT86RF212
is stumbled across a possible bug regarding the activation of BPSK-20.
If one sets RF212_TRX_CTRL_2_VALUE to RF212_DATA_MODE_BPSK_20 (==0…
