PHASE TRACKING FOR A COMMUNICATION DEVICE

摘要

A communication device for enabling phase tracking is described. The communication device includes a processor and instructions stored in memory. The communication device generates a plurality of pilot symbols. The pilot symbols conform to a rank-deficient pilot mapping matrix, i.e. a matrix in which each row coreresponds to pilot symbols transmitted on a different spatial stream and each column corresponds to pilot symbols transmitted on different OFDM symbols.
