Cryptcodes based on quasigroups transformation, known as Random Codes Based on Quasigroups (RCBQ) are error-correcting codes de_ned by using a cryptographic algorithm during the encoding/decoding process. Therefore, they allow not only correction of certain amount of errors in the input data, but they also provide an information security, all built in one algorithm. Standard and Cut-Decoding algorithms for these codes are de_ned elsewhere. Also, performances of these codes are investigated elsewhere, when a transmission through a binary symmetric channel is used. In this paper, we investigate the performances of RCBQ for transmission through Gaussian channel. We analyze the in_uence of the code parameters on the performances of RCBQ for code (72,288) with rate 1/4. We present and compare several experimental results obtained with di_erent coding/decoding algorithms for these codes.
