Some random notes about the reference BPSK-1000 reference modem for ARISSat-1 by Phil Karn, KA9Q.


Contents

Overview

The package contains a DSP lilbrary libdspfec.a and various utility programs for testing and demonstration purposes. The included Makefile will build the library and all executables.


Operational constraints

  1. The reference implementation uses 48 ksps. For other sample rates the filter coefficients in nyquist.c must be reworked[1]. It is therefore easier to simple resample to 48 ksps.
