Hierarchical cellular network based on multiple access techniques and cellular phone based on multiple access techniques using the same

摘要

The present invention relates to a multiple access mobile communication terminal using a hierarchical cellular network and multiple access scheme which as , more specifically, the service to macrocells FH-OFDMA method, a micro cell , by service to the OFDMA scheme , multiple access scheme that allows a terminal that can connect to the cell with FH-OFDMA and the multiple access method OFDMA hierarchical cellular network and use it during the low speed movement can use the OFDMA scheme for data communication , the present invention relates to a multiple access mobile communication terminal during the high speed movement , using the FH-OFDMA scheme allows for the coherent detection .
