Abstract:
1. A receiver system, comprising: a channel estimation block configured to perform a first channel estimation with regard to a first channel between a first transmit antenna and a first receive antenna, a second channel estimation with regard to a second channel between the first transmit antenna and a second receive antenna, a third channel estimation with regard to a third channel between a second transmit antenna and the first receive antenna, and a fourth channel estimation with regard to a fourth channel between the second transmit antenna and the second receive antenna; and an open-loop frequency offset compensator configured to compensate for a frequency offset that is equal to a difference between a first carrier frequency associated with the first transmit antenna and a second carrier frequency associated with the second transmit antenna by adjusting at least one of a phase associated with the third channel estimation or a phase associated with the fourth channel estimation, the open-loop frequency offset compensator being programmable to be selectively enabled or disabled based on a specified receiver operation mode, which is selected from a plurality of receiver operation modes, in accordance with which the receiver system is to operate.
