Abstract
In one embodiment, a buffer-based method for generating codes (such as Orthogonal Variable Spreading Factor (OVSF) codes) for spreading and despreading data, without using a chip-rate counter. First, a buffer is populated with initial values based on a received spreading factor and desired code index. Next, a timing strobe is received, and the values in the buffer are changed upon receipt of the timing strobe based on an algorithm that is independent of any count value associated with the timing strobe. Finally, a code sequence value is generated based on the values in the buffer.
