Abstract
A method for transmitting and receiving variable rate data. The data is spread using a long pseudo noise code generated by a linear feedback PN generator (16) the mask of which is selected by mask selector (14) in accordance with the transmission rate of the variable data and the specific user transmitting the data. Thus by identifying at the receiver which mask will allow the received waveform to be correctly despread the rate of the data can be determined.
