摘要： A subscriber unit (104) with multiple receive antennas (160, 162) and a single transmit antenna (160) derives beamforming weights to be used at a base station (102) with multiple transmitting antennas (602, 604, 606, and 608). The downlink beamforming weights are derived at the subscriber unit (104) from a prior downlink transmission from the base station (102) to the subscriber device (104) and an uplink sounding signal is used to carry derived downlink beam forming weights to the base station (102). Downlink antenna specific pilots (without weight) are used at the subscriber device (104) to determine the beamforming weights. Decimated sounding signals, where the number of sounding subcarriers is al least the same as the number of antennas at the base station (102), allow multiple users to sound at the same time.

摘要： Various embodiments are described to provide for the transmission of data in an improved manner. Data transmission is improved by including in a transmitter a null generator (310) to embed frequency domain nulls into a data symbol sequence to produce a null-embedded data symbol sequence. A symbol inserter (320) inserts a control symbol sequence into the frequency domain nulls of the null-embedded data symbol sequence to produce a combined symbol sequence. A modulator (330) then encodes the combined symbol sequence using IFDMA / DFT-S-OFDM. This approach allows the assignment of a single IFDMA / DFT-S-OFDM code to each user for data and control (pilot, e.g.) signaling, simplifying code management. Frequency hopping techniques may also be employed to lower the pilot overhead.

摘要： A radio communications device (102) that has multiple receive antennas processes received data communications signals to select between space time coding and spatial multiplexing as a selected transmission technique from a base device (104) that has multiple transmit antennas. A channel throughput (402-412, 450-454) for each transmission technique is estimated based on signal to interference and noise ratios (502-512, 550-554) of signals being transmitted through a MIMO channel (140) as measured by a receiver (708). The transmission technique with the higher estimated throughput is determined. If spatial multiplexing is determined to have the higher estimated throughput and the throughput of each layer of the spatially multiplexed signal is greater than a threshold, spatial multiplexing is selected. Otherwise, space time coding is selected.

摘要： A transmitter comprises functionality (101, 103) for generating a block of input modulation symbols for example from received data bits. An M-point discrete Fourier transform (105) is applied to the block of input modulation symbols resulting in a frequency domain symbol block. This block is fed to an N-point inverse discrete Fourier transform (105) (N>M) thereby generating a time domain transmit signal. In addition, the transmitter (200) comprises an inter-symbol processor (201) which determines inter-symbol values corresponding to inter-symbol times of the time domain transmit signal and an attenuation processor (203) which attenuates at least one of the input modulation symbols in response to the inter-symbol values. By attenuating selected input modulation symbol(s) a significantly reduced amplitude variation and specifically peak-to-average amplitude variation can be achieved.

摘要： Administration of human umbilical cord blood cells (HUCBC) or HUCBC-derived plasma is used to treat amyloid-based diseases, such as Alzheimer's disease, Huntington's disease, cerebral amyloid antigopathy, and type-II diabetes. Modulating inflammatory reactions by infusing HUCBC resulted in a marked reduction of amyloid plaques and immune-associated cellular damage. HUCBC infusion also significantly reduced cerebral amyloid angiopathy in mice models. These effects were associated with suppression of the CD40-CD40L interaction and a reduction in surface expressed CD-40 was observed on immune cells. Further, A? phagocytic activity was increased and soluble and insoluble AB protein levels were modulated by treatment. HUCBC-infused sera also significantly increased phagocytosis of AB 1-42 peptide and inhibited immune cell CD40 expression and reduced cerebral amyloid angiopathy.

摘要： Evidence indicates dysregulation of the immunoregulatory molecule CD45 occurs in Alzheimer's disease (AD). Transgenic mice overproducing amyloid-β peptide (Αβ) and deficient in CD45 (PSAPP/CD45 T) recapitulate AD neuropathology. Increased cerebral intracellular and extracellular soluble oligomeric and insoluble Αβ, decreased plasma soluble Αβ, increased microglial neurotoxic cytokines TNF-a and I L-1 β, and neuronal loss were found in PSAPP/CD45T mice compared with CD45-sufficient PSAPP littermates. After CD45 ablation, in vitro and in vivo studies demonstrate a microglial phenotype whereby microglia phagocytose less Αβ but display proinflammatory properties. This microglial activation occurs with elevated Αβ oligomers and neural injury and loss as determined by decreased ratio of anti-apoptotic Bcl-xL to proapoptotic Bax, increased activated caspase-3, mitochondrial dysfunction, and loss of cortical neurons in PSAPP/CD45 T mice. These data show that deficiency in CD45 activity leads to brain accumulation of neurotoxic Αβ oligomers and validate CD45-mediated microglial clearance of oligomeric Αβ as a novel AD therapeutic target.
