Due to the effect of CTI in OFDMA, the outage rate is analysed in [6], where GA and Particle Swarm Optimization (PSO) based dynamic
subcarrier allocation had been proposed.
Each base station operates under the constraint that it has at its disposal a maximum amount of power to share among all active
subcarrier links.
There are two different techniques for
subcarriers selection of SC-OFDMA signals transmission: the distributed
subcarrier mapping method, at which the DFT outputs of the required input data are assigned over the total bandwidth while the zeros are padded in unused sub-carriers.
The software supports key features of 802.11ax including narrower
subcarrier spacing, 1024-QAM and multi-user orthogonal frequency division multiple access (OFDMA).
Mitsubishi Electric Corporation has developed a multi-
subcarrier optical transceiver technology that significantly increases the data rate of terrestrial fiber optic communication.
where n is the time index, X[k] is the data symbol on the fcth
subcarrier, k denotes the
subcarrier index, and N is the number of the
subcarriers.
Subcarrier Communications said it has been selected to provide rooftop management services to the Chase Tower in Indianapolis, IN.
This also determined the
subcarrier spacing to be 312.5 kHz, which is the inverse of the symbol duration minus the guard time.

Subcarrier Communications has acquired US-based AC Site Management for USD 2.1m, the company said.
