Networked wireless communications device programmed to identify and eliminate probable multipath errors to enhance accuracy in correcting sleep clock for thermally induced errors |
摘要 |
A method for correcting operation of the sleep oscillator ( 116 ) of a wireless communications device ( 100 ). Sleep oscillator frequency is estimated ( 412 ) so as to compensate for estimated temperature induced errors. In estimating temperature induced errors, errors ( 504 ) in sleep oscillator frequency are treated as being temperature induced errors ( 522 ), but probable multipath errors are bounded ( 410, 520 ) to predetermined sleep clock error maxima ( 602 ) corresponding to sleep duration over which the error occurred. |
