Abstract:
Method for transmitting a wideband code division multiplex output signal at a given chip-rate corresponding to a plurality of combined physical radio links for respective user entities, comprising the steps of performing parallel symbol and code generation, parallel modulation, parallel spreading, each enhanced multiplex rate cycle providing a first number of parallel spread chip values, thus forming a first number of spread chip value streams. The enhanced multiplex rate being a second number greater than the chip rate of the output signal, combining the physical radio links over a number of segments corresponding to the second number at the enhanced multiplex rate in multiplex fashion, extending the combination of the physical radio links during a time corresponding to a third number of chips, causing a combined plurality of physical radio links, buffering the results so as to establish a complex signal at chip rate to the air transmission antenna.
