Performance of Subcarrier and Power Allocation Orthogonal Frequency-Division Multiplexing on Millimeter Wave
Abstract: Local multipoint
distribution system (LMDS) that operated in millimeter waves can be used to
fulfill the need of bit rate higher than 40 Mbps. However it has problem when
applied in tropic country such as Indonesia because of the high rainfall.
Therefore LMDS system was developed by cross-layer mechanism. In this research we used joint subcarrier and
power allocation (JSPA) technique in multi-user cross-layer OFDM. This
technique is proposed to increase the performance of telecommunication system
even there were disturbance of rain attenuation. The research is discussing the
performance of transmission capacity, data rate, utility and fairness of JSPA
algorithm that applied in rain attenuation measurement in Surabaya. The result
shows the increment of performance system using JSPA technique. For 40 dB rain
attenuation, JSPA can achieves respectively average capacity of transmission up
to 173,3%, 189,9 % for data rate and 9,6% for fairness system. The application
of JSPA technique improve the performance of utility 13,61-15,48 bps/Hz
