Análisis de las modulaciones y los métodos de acceso para redes radio de gran capacidad en interiores

Abstract

This paper presents a preliminary study on some parameters of the Wind-Flex project which are to be determined, such as digital type modulation, multi-access techniques and requirements of amplifiers linearity and synthesisers phase noise. Orthogonal Frequency Division Multiplex seems to be the most appropriate modulation to reduce the channel fading effects. Further study shall be carried out in this field, as power and bit rate control in each OFDM sub-carrier are expected.
