Abstract
The invention concerns an access system to channels focused on when programs with useful information begin, on live package radio with multiple access to code divisions (CDMA). With this system, the program begins using a sequence of non-linear codes (SNL) that are common to the whole network so as to be synchronized and, a second code sequence (SL) is added when the data transmission of useful information begins (SL), which is generally linear and leaves from a noted state; regarding reception, the synchronization of the non-linear SNL sequence is first completed and then the second generation code leaves in the same instant in which the useful information is about to start so as to be able to obtain the transmitted data.
