    Abstract: A system is provided for transmitting a low code rate spatially multiplexed channel on multiple antennas. The system includes a transmitter and a processor. The processor is configured such that the processor encodes a block of information bits to form channel coded bits, wherein the ratio of the number of channel coded bits to the number of information bits is greater than one; and the processor maps the channel coded bits to modulation symbols, and each channel coded bit is mapped once to a modulation symbol. The transmitter is configured to transmit a first portion of the modulation symbols using a spreading sequence on a first antenna of the multiple antennas and to transmit a second portion of the modulation symbols using the spreading sequence on a second antenna of the multiple antennas.

    Abstract: A method for providing transmit diversity in wireless network communications is presented. An indication of a slot structure is received. The slot structure identifies at least a first location of a reference signal within a slot. A first reference signal is transmitted within a first slot using a first antenna. A location of the first reference signal within the first slot is determined by the slot structure. A second reference signal is transmitted within the first slot using a second antenna. A location of the second reference signal within the first slot is determined by the slot structure. In some cases, the slot structure identifies a second location of a reference signal within the slot structure. The second location being offset from the first location, and a third reference signal is transmitted within the first slot at the second location on the first antenna.
