A wireless communication system (). The system comprises a transceiver (), and the transceiver comprises a code counter (LCSTC) and a clock oscillator () for advancing a count in the code counter. The transceiver further comprises circuitry () for receiving a time message based on a system time external from the transceiver and circuitry () for determining a system time count and for storing the system time count to the code counter in response to the time message. Further, code counter continues to be advanced from the system time count in response to the clock oscillator. The transceiver further comprises circuitry () for repeatedly evaluating the count in the code counter, after advancement from the system time count, to ascertain whether the count has drifted to an inaccurate count. Lastly, the transceiver further comprises circuitry (), responsive to detecting an inaccurate count, for adjusting the inaccurate count to a perceived accurate count.

Wireless communication system operating in response in part to time signals from the global position satellite system

A wireless base station (). The base station comprises at least one receive antenna (AT) for receiving communication signals from at least one transmitting station (UST), and the signals are spread with a plurality of chips. The base station further comprises circuitry () for selecting a set of chips corresponding to a first signal received by the at least one receive antenna and circuitry () for forming a set of de-spread chips corresponding to the set of chips and in response to a code. Still further, the base station comprises a functional data path () comprising an accumulator for receiving the set of de-spread chips and circuitry for receiving an instruction. The functional data path is operable in response to a first instruction, received by the circuitry for receiving an instruction, to accumulate (or) a first number of de-spread chips in the set of de-spread chips for producing at least one corresponding symbol. The functional data path is operable in response to a second instruction, received by the circuitry for receiving an instruction, to accumulate () a second number of de-spread chips in the set of de-spread chips for producing an EOL measure.
