Description
  • The paper is focused on possibility of digitalized voice transmission through radio amateur VHF band. Choosing of suitable digital modulation and sound coder were discussed. Quality test of speech codec Speex depending on bit-error-rate is presented. Simulation of theoretical minimal SNR for DBPSK modulation was performed in Matlab. Presented system was analyzed with Rician and Rayleigh fading channel. The maximal theoretical range of the presented system was calculated.
