20150365147 | PILOTS FOR MIMO COMMUNICATION SYSTEMS - Pilots suitable for use in MIMO systems and capable of supporting various functions are described. The various types of pilot include—a beacon pilot, a MIMO pilot, a steered reference or steered pilot, and a carrier pilot. The beacon pilot is transmitted from all transmit antennas and may be used for timing and frequency acquisition. The MIMO pilot is transmitted from all transmit antennas but is covered with different orthogonal codes assigned to the transmit antennas. The MIMO pilot may be used for channel estimation. The steered reference is transmitted on specific eigenmodes of a MIMO channel and is user terminal specific. The steered reference may be used for channel estimation. The carrier pilot may be transmitted on designated subbands/antennas and may be used for phase tracking of a carrier signal. Various pilot transmission schemes may be devised based on different combinations of these various types of pilot. | 12-17-2015 |

20120176928 | CHANNEL CALIBRATION FOR A TIME DIVISION DUPLEXED COMMUNICATION SYSTEM - Techniques to calibrate downlink and uplink channels to account for differences in the frequency responses of transmit and receive chains are described. In one embodiment, pilots are transmitted on downlink and uplink channels and used to derive estimates of the downlink and uplink channel responses, respectively. Sets of correction factors are then determined based on estimates of downlink and uplink channel responses. A calibrated downlink channel is formed using a first set of correction factors for the downlink channel, and a calibrated uplink channel is formed using a second set of correction factors for the uplink channel. The first and second sets of correction factors may be determined using a matrix-ratio computation or a minimum mean square error computation. The calibration may be performed in real-time based on over-the-air transmission. Other aspects, embodiments, and features are also claimed and described. | 07-12-2012 |

20100119001 | MIMO SYSTEM WITH MULTIPLE SPATIAL MULTIPLEXING MODES - A MIMO system supports multiple spatial multiplexing modes for improved performance and greater flexibility. These modes may include (1) a single-user steered mode that transmits multiple data streams on orthogonal spatial channels to a single receiver, (2) a single-user non-steered mode that transmits multiple data streams from multiple antennas to a single receiver without spatial processing at a transmitter, (3) a multi-user steered mode that transmits multiple data streams simultaneously to multiple receivers with spatial processing at a transmitter, and (4) a multi-user non-steered mode that transmits multiple data streams from multiple antennas (co-located or non co-located) without spatial processing at the transmitter(s) to receiver(s) having multiple antennas. For each set of user terminal(s) selected for data transmission on the downlink and/or uplink, a spatial multiplexing mode is selected for the user terminal set from among the multiple spatial multiplexing modes supported by the system. | 05-13-2010 |

20100273141 | Glycine stabilized lyophilized plasma - The invention is directed to stabilized whole-cell plasma, which retains the integrity and overall stability of the proteins and other macromolecules of the plasma. Stabilization is accomplished by the addition of glycine to plasma which allows for stabilization prior to freeze drying. Glycine, in the presence of the salt concentration in the plasma, does not recrystallize and acts as a superior stabilizer for the lyophilized plasma. The stability of the freeze dried plasma may be further improved by addition of protectants including calcium chloride, trisodium citrate, hydroxyethyl starch, ammonium sulfate and citric acid to maintain physiologic pH. Superior stability for a wide variety of plasma proteins and functions is shown. A system for the large scale preparation of sterile lyophilized plasma is also provided. | 10-28-2010 |
