Reference clock compensation in DVB-H receivers

摘要

A wireless receiver providing multiple services (FIG. 3) is disclosed. The wireless receiver includes an oscillator circuit (304, FIG. 4) arranged to produce a reference frequency (308). A first receiver (302) receives a first signal (300) having a first carrier frequency in response to the reference frequency. A second receiver (322) receives a second signal (320) having a second carrier frequency different from the first carrier frequency in response to the reference frequency.

主权项

1. A wireless receiver, comprising:
an oscillator circuit arranged to produce a reference frequency; a first receiver arranged to receive a first signal having a first carrier frequency and a fourth signal having a fourth carrier frequency different from the first carrier frequency in response to the reference frequency, the first receiver calculating a frequency correction signal in response to a handover from the first carrier frequency to the fourth carrier frequency; and a second receiver arranged to receive the frequency correction signal and a second signal having a second carrier frequency different from the first and fourth carrier frequencies in response to the frequency correction signal and the reference frequency.
