Abstract
This paper presents cross-layer optimization implementation for millimeter wave OFDM network in the
presence of rain fading. Cross-layer optimization is proposed to overcome the power inefficiency and
complexity of conventional fading mitigation technique. The network is modeled as downlink multi-user single
cell OFDM network. The rain fading data is generated based on Synthetic Storm Technique using rain rate data
measured in Surabaya Area. To show the interest of cross-layer optimization, a combining optimization between
physical and MAC layer using dynamic sub-carrier allocation and adaptive power allocation algorithm is
demonstrated. The optimization objectives are the improvement of utility and fairness in heavily rain affected
cell. The result shows an improvement of utility for multi-user OFDM network in term of total rate.
Keywords: OFDM, single cell multi-user, millimeter wave rain fading, SST, cross-layer design, JSPA.
