摘要： Methods and systems are provided to improve the data transmission rate of a system executing an network protocol such as TCP, by adapting the protocol according to an error rate of the system. The technique includes first establishing a connection between a receiver and transmitter according to the network protocol including establishing a data window size, the window size being an indicator of the amount of data the receiver can receive. As data segments are received, the receiver counts the number of data segments received as well the number of errored octets produced by the physical layer of the network over specified time periods. For each time period, the receiver determines whether the window size of the receiver should be changed to improve the data communication rate based on the previous window size, the number of segments received and the number of errors measured. If the window size is changed, then the receiver reestablishes communication with the transmitter using the new window size, thus altering the network protocol to optimize the overall data transmission rate.

摘要： A blanking scheme for mitigating impulsive noise in wireless networks is based on the signal-to-noise ratio (SNR) of symbols. To fully gain the benefits of the SNR-based blanking scheme, two methods are developed, namely a multi-level thresholding scheme in the time-, spatial- and frequency-domains, and a weighted-input error-correction decoding. The symbols are conditioned as a function of the estimated SNR in time-, frequency-, or spatial-domains or combinations therefore, and the conditioning is applied to an amplitude, phase, or energy level, or combinations thereof.

摘要： A network includes a master and a set of slaves that communicate orthogonal frequency-division multiplexing (OFDM) and time division multiple access (TDMA) symbols on sub-carriers. A master broadcasts to the set of slaves using downlinks and all of the sub-carriers, a broadcast polling packet including data packets for each slave and sub-carrier assignments for the slaves. Each slave, in response to receiving the downlink polling packet, transmits simultaneously a response packet to the master using uplinks and the assigned sub-carriers. The master then transmits to the set of slave using the downlinks and all of the sub-carriers, a group acknowledgement packet, wherein the broadcast polling packet, the response packet, and the group acknowledgement packet comprise one superframe in one communication cycle, and wherein the broadcasting on the downlinks and the transmitting on the uplinks are disjoint in time.

摘要： A method surpresses clutter in a space-time adaptive processing system. The method achieves low-complexity computation via two steps. First, the method utilizes an improved fast approximated power iteration method to compress the data into a much smaller subspace. To further reduce the computational complexity, a progressive singular value decomposition (SVD) approach is employed to update the inverse of the covariance matrix of the compressed data. As a result, the proposed low-complexity STAP procedure can achieve near-optimal performance with order-of-magnitude computational complexity reduction as compared to the conventional STAP procedure.

摘要： A method and system provide multiple-access control and frequency band allocation, and transmission time sharing among multiple users in orthogonal frequency-division multiple-access (OFDMA) and time-division multiple-access (TDMA) networks. The method can be applied to uplinks and downlinks of multi-user, multi-carrier communication networks. Under a total transmission-power minimization constraint, the method can allocate carriers and transmission time to users optimally, and at the same time, can guarantee a data rate or equivalently a latency requirement of each user.
