Abstract

Se divulga un sistema de acceso multiple por division de frecuencia ortogonal (OFDMA) híbrido que incluye un transmisor y un receptor. El transmisor incluye un primer sub-conjunto de OFDMA de dispersion, un primer sub-conjunto de OFDMA sin dispersion y un primer sub-conjunto comun. El primersub-conjunto de OFDMA de dispersi''on dispersa datos de entrada y mapea los datos dispersados para un primer grupo de sub-portadoras. El primer sub-conjunto de OFDMA sin dispersion mapea datos de entrada para un segundo grupo de sub-portadoras. El primer sub-conjunto comun transmite los datos de entrada mapeados al primer y al segundo grupos de sub- portadoras, utilizando OFDMA. El receptor incluye un segundo sub-conjunto de OFDMA sin dispersion y un segundo sub-conjunto comun. El segundo sub-conjunto comun procesa los datos recibidos para recuperar datos mapeados para la sub-portadoras utilizando OFDMA. El segundo sub-conjunto de OFDMA de dispersion recupera los primeros datos de entrada separando datos de usuario en un dominio de codigo y el segundo sub-conjunto de OFDMA sin dispersion recupera los segundos datos de entrada.A hybrid orthogonal frequency division (OFDMA) multiple access system that includes a transmitter and a receiver is disclosed. The transmitter includes a first subset of OFDMA dispersion, a first subset of OFDMA without dispersion and a first common subset. The dispersion OFDMA primersub-set disperses input data and maps the dispersed data for a first group of subcarriers. The first subset of OFDMA without dispersion maps input data for a second group of subcarriers. The first common subset transmits the mapped input data to the first and second subcarrier groups, using OFDMA. The receiver includes a second subset of OFDMA without dispersion and a second common subset. The second common subset processes the received data to retrieve mapped data for the subcarriers using OFDMA. The second subset of OFDMA dispersion retrieves the first input data by separating user data in a code domain and the second subset of OFDMA without dispersion retrieves the second input data.
