Abstract
Despreading apparatus with a relatively simple control is described. Plurality of despreading modules are provided in parallel, e.g., one per user. Each despreading module supports a plurality of despreading rates, e.g., ranging from the minimum to the maximum despreading rate that may be assigned to a user. Each despreading module is controlled in a simple manner with the output of the despreading module and despreading rate achieved being determined by a control module controlling a controllable downsampling module such that despreading rate corresponding to the individual user to which the despreading module corresponds is achieved at any given time. MUX control signals are provided to a plurality of MUXes included in the despreading module, and may be stored in a table with each set of MUX control signals corresponding to a different despreading rate. Control is greatly simplified, compared to systems where a set of despreading circuitry is dynamically configured.
