  • A channel characterization technique for HF communications 

    Delgado Penin, José Antonio (1985)
    Conference report
    Open Access
    A wideband channel sounder to characterize the HF radio channel is described. Based on a pseudorandom sequence technique it allows the measurement of the complex impulsional response of the channel with time and frequency ...
  • A combined polling and ISMA-DS/CDMA protocol to provide QoS in packet mobile communications systems 

    Pérez Romero, Jordi; Agustí Comes, Ramon; Sallent Roig, José Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Conference report
    Open Access
    This paper presents a new mechanism that combines the flexibility of an access protocol such as ISMA-DS/CDMA with the ability of a polling mechanism to provide a specific bound for the access delay. This protocol is proposed ...
