Résumé:
Frequency diversity obtained with multiple carrier frequencies has been widely studied
for indoor channels applications. Indoor channels have high channel rate, the
Doppler frequency can be discarted and the fading is slow and selective frequency. So,
the multiples carrier frequencies is often used in the slow bandwidth channels.
This work presents simulation results of the slow complexity multicarrier digital
communication systems for indoor channels. This system uses a binary nonlinear code
to specify multitone signal constellations. The OOK modulation and the noncoherent
demodulation are also employed. Error control coding is presented to improve the
multicarrier system performance.
Simulations with others metrics were been done. However, a new metric, to improve
the performance system, is not found. So, others alternatives must been found.
