"PROCESSOS PARA DESIGNAR CóDIGOS DE ESPALHAMENTO PARA UMA PRIMEIRA CORRESPONDENTE CONEXãO DE LIGAçãO DIANTEIRA ENTRE UMA PLURALIDADE DE CONEXõES DE LIGAçãO DIANTEIRA EM UM SISTEMA DE COMUNICAçãO DS-CDMA, PARA DESIGNAR CóDIGOS DE ESPALHAMENTO PARA CORRESPONDENTES CONEXõES DE LIGAçãO DIANTEIRA EM UM SISTEMA DE COMUNICAçãO DS-CDMA E, PARA DESIGNAR UM NúMERO TOTAL DE CóDIGOS DE ESPALHAMENTO PARA CORRESPONDENTES CONEXõES DE LIGAçãO DIANTEIRA COM TAXA DE BIT VARIáVEL EM UM SISTEMA DE COMUNICAçãO DS-CDMA". A presente invenção relaciona-se a processos para designar códigos de espalhamento para conexões de ligação dianteira com taxa de bit variável em sistemas de comunicação DS-CDMA. Uma primeira conexão é designada a um primeiro número de códigos (x) de um primeiro conjunto (S1) de códigos ortogonais. Uma segunda conexão é designada a um segundo número de códigos (y). Uma primeira parte (y-k~ 1~) do segundo número de códigos (y) é tomada do primeiro conjunto (S1) de códigos ortogonais. Uma segunda parte (k~ 1~) do segundo número de códigos (y) é tomada de um segundo conjunto (S2) de códigos ortogonais que é não ortogonal ao primeiro conjunto (S1)."PROCESSES TO DESIGN SPREADING CODES FOR A FIRST CORRESPONDENT FRONT CONNECTION CONNECTION AMONG A FRONT CONNECTION PLURALITY IN A DS-CDMA COMMUNICATION SYSTEM, TO DESIGN A SPECIFICATION SPREADING CODE FOR CORRESPONDING CONNECTION CDMA E, TO DESIGNATE A TOTAL NUMBER OF SPREADING CODES FOR CORRESPONDENT FRONT CONNECTION CONNECTIONS WITH VARIABLE BIT RATE IN A DS-CDMA COMMUNICATION SYSTEM ". The present invention relates to processes for assigning spreading codes for forward link connections with variable bit rate in DS-CDMA communication systems. A first connection is assigned to a first number of codes (x) from a first set (S1) of orthogonal codes. A second connection is assigned to a second number of codes (y). A first part (y-k ~ 1 ~) of the second number of codes (y) is taken from the first set (S1) of orthogonal codes. A second part (k ~ 1 ~) of the second number of codes (y) is taken from a second set (S2) of orthogonal codes that is not orthogonal to the first set (S1).
