  • Achieving Simultaneous Spectrum Utilization and Revenue Improvements in Practical Wireless Spectrum Auctions 

    Pourmina, M.A.؛ bakhshi, hamidreza؛ Navidi, H.؛ Mazoochi, M. (Shahed University, 2013-03-01)
    Spectrum is a valuable, scarce and finite natural resource that is needed for many different applications, so efficient use of the scarce radio spectrum is important for accommodating the rapid growth of wireless ...

  • Power Allocation In Cooperative Relay Channels 

    Akhlaghi, Sorosh؛ Hashemi, H. (Shahed University, 2013-03-01)
    This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter ...

  • A Low Complexity Forward Error Correction for PAPR reduction in OFDM Systems 

    Poormohsen Amiri, A.؛ Ferdosizadeh Naeiny, M. (Shahed University, 2013-03-01)
    In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce ...

  • Design of a Two Octave Gysel Power-Divider Using DGS and DMS 

    Fartookzadeh, M. (Shahed University, 2013-03-01)
    This paper proposes a two way L and S band Gysel power divider/combiner that uses line to ground resistors. Step by step methods to obtain a wide isolation and transmission bandwidth are presented. A design that uses five ...
