Abstract
A method and apparatus are described including receiving a first signal including first data in a first time slot of a first channel (705), receiving a second signal including second data in a second time slot of a second channel (710), determining a first pre-coding matrix (715), determining a second pre-coding matrix (720), applying the first pre-coding matrix to the first data to produce pre-coded first data (725), applying the second pre-coding matrix to the second data to produce pre-coded second data (730), generating a third signal by combining the pre-coded first data and the pre-coded second data (735) and transmitting the third signal on the first channel and on the second channel (740). Also described are a method and apparatus including transmitting a first signal (605), receiving a second signal including a first training sequence (610) and decoding the second signal by removing the first training sequence and removing the first signal (615).
