Link quality metric based antenna selection for transceivers

A method for selecting an antenna from a plurality of antennas associated with a receiver, comprising:

• receiving multi-carrier modulated signals via a currently active antenna of the receiver;
• estimating a predicted packet error rate (PER) associated with a current receive path of the receiver, wherein the current receive path is used to process the multi-carrier modulated signals received via the currently active antenna, wherein an effective mutual information (Ieff), an effective SNR (SNReff), and a packet length of the multi-carrier modulated signals are used to compute the predicted PER;
• and
• selecting a next antenna from the plurality of antennas for forming a next receive path of the receiver based on the predicted PER and a packet error history associated with at least one previous receive path.

A receiver, comprising:

• a plurality of antennas;
• an antenna selection module for forwarding a control signal which triggers a switch from a currently active antenna of the plurality of antennas to a next antenna of the plurality of antennas based on a predicted packet error rate (PER) associated with a current receive path of the receiver and a packet error history associated with at least one previous receive path, wherein the packet error history comprises at least one CRC error which corresponds to the at least one previous receive path, and wherein the current receive path is used to process multi-carrier modulated signals received via the currently active antenna and wherein an effective mutual information (Ieff), is used to compute the predicted PER;
• and
• a switch module for performing the switch from the currently active antenna to the next antenna based on the control signal.

A non-transitory computer readable medium having stored thereon instructions selecting an antenna from a plurality of antennas associated with a receiver comprising machine executable code which when executed by a computing machine, causes the machine to perform steps comprising:

• receiving multi-carrier modulated signals via a currently active antenna of the receiver;
• estimating a predicted packet error rate (PER) associated with a current receive path of the receiver, wherein the current receive path is used to process the multi-carrier modulated signals received via the currently active antenna, wherein an effective mutual information (Ieff) is used to compute the predicted PER;
• and
• selecting a next antenna from the plurality of antennas for forming a next receive path of the receiver based on the predicted PER and a packet error history associated with at least one previous receive path.
