Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for antenna switching diversity comprising: identifying the start of an OFDM symbol period; switching from an original antenna to an alternative antenna; calculating a signal quality metric associated with the original antenna and the alternative antenna; and selecting either the original antenna or the alternative antenna for demodulation of a current OFDM symbol based on the calculated signal quality metric. In one aspect, the antenna switching diversity is based on either symbol rate switching or block rate switching, and a selection of one or the other is made.
