摘要： An example technique may include: receiving, by a mobile station from a base station, a plurality of copies of a broadcast information including a broadcast control message, wherein a copy of the broadcast information is transmitted via each of a plurality of basis function beams; determining, by the mobile station, a gain and phase value for each copy of at least a subset of the plurality of the received copies of the broadcast control message transmitted via different basis function beams. The technique may also include, for example, determining, by the mobile station, a combined broadcast control message based on at least the subset of the plurality of the received copies of the broadcast control message and the gain and phase value for each copy of at least the subset of the plurality of the received copies of the broadcast control message.

摘要： A group of data symbols for a current block of data symbols in multiple blocks received over a communication channel is equalized, based on a pilot block, to generate a group of equalized symbols. The group of equalized symbols is de-rotated as a function of a current phase estimate to determine initial de-rotated equalized symbols. The phase estimate is an estimate of phase caused by noise for blocks previous to the current block. Additionally, a phase metric is calculated from real and imaginary parts of the initial de-rotated equalized symbols, wherein the phase metric estimates phase caused by noise for the current block. The current phase estimate is updated with the phase metric. The initial de-rotated equalized symbols are de-rotated by the phase metric to determine final equalized and de-rotated symbol estimates. The final equalized and de-rotated symbol estimates are output. Apparatus, methods, and computer program products are disclosed.
