    • A contribution on adaptive coding strategies over H.F. channels 

      Dalmau Royo, Jordi; Delgado Penin, José Antonio (1989)
      Conference report
      Open Access
      We present a coding scheme which makes use of adaptive coding techniques. Since we are concerned with the H,F, channel, suitable coding schemes are needed to combat diffuse errors [1], i. e, random and burst errors, ...

    • Algoritmo para optimizacion de la transferencia de datos libres de errores en canales H.F 

      Valle Alarcón, Rafael; Dalmau Royo, Jordi (1991)
      Conference report
      Open Access
      We present a research on error-free data transmission in H.F. radio communications. In concrete, a study on the C.C.I.T.T. recomendation V.42 and a evaluation of the optimal frame length vs. average b.e.r. of th H. F . ...

    • Performance analysis of a hybrid ARQ system in half duplex transmission at 2400 BPS 

      Dalmau Royo, Jordi; Serrat Fernández, Juan (IEEE IEEE, 1991)
      Conference report
      Open Access
      Hybrid ARQ/FEC protocols have been proposed to provide high data link integrities whilst keeping at the same time a high mean throughput rate. Nevertheless, hybrid ARQ strategies offer a lot of choices and none of them can ...
