Abstract: The invention provides a method for generating a code sequence. A code-generation instruction is received from memory. One or more control signals are determined based on the code-generation instruction. A code sequence is generated based on the control signals, a current state input, and a mask input.

Abstract: A programmable correlator for a communication system includes an input queue coupled with an analog-to-digital converter (ADC). The input queue includes a random access memory (RAM) wherein sampled data streams from the ADC are written into the RAM. The input queue has two banks of memory of width 2M. A flexible complex correlator is operable on M samples. The correlator is coupled to read M complex samples out of 2M samples from the input queue. A pseudo-noise (PN) crossbar unit operates to rotate a generated PN code to match a rotation of the input queue data in the complex correlator.

Abstract: A method for performing timing synchronization between digital input data and a system clock in a communication device includes providing a system clock rate that is higher than a data clock rate and sampling the input data at intervals in the system clock periods within the data clock period. The method includes adjusting the timing between the digital input data and the system clock by either shortening the number of system clock periods and sampling intervals, or lengthening the number of system clock periods and sampling the input data at normal intervals and providing data insertion to fill one of the extra system clock periods, such that more data samples are provided in the data clock period.

Abstract: A method for performing timing synchronization (fig. 3) between digital input data and a system clock in a communication device includes providing a system clock rate that is higher than a data clock rate (34) and sampling the input data at intervals in the system clock periods within the data clock period. The method includes adjusting (36 and 38) the timing between the digital input data and the system clock by either shortening the number of system clock periods and sampling intervals, or lengthening the number of system clock periods and sampling the input data at normal intervals and providing data insertion to fill one of the extra system clock periods, such that more data samples are provided in the data clock period.
