Scattered pilot pattern and channel estimation method for MIMO-OFDM systems

ActiveUS7248559B2Reduced scattered pilot overheadLess computationally complexPower managementSpatial transmit diversityTime domainCommunications system
A method and apparatus are provided for reducing the number of pilot symbols within a MIMO-OFDM communication system, and for improving channel estimation within such a system. For each transmitting antenna in an OFDM transmitter, pilot symbols are encoded so as to be unique to the transmitting antenna. The encoded pilot symbols are then inserted into an OFDM frame to form a diamond lattice, the diamond lattices for the different transmitting antennae using the same frequencies but being offset from each other by a single symbol in the time domain. At the OFDM receiver, a channel response is estimated for a symbol central to each diamond of the diamond lattice using a two-dimensional interpolation. The estimated channel responses are smoothed in the frequency domain. The channel responses of remaining symbols are then estimated by interpolation in the frequency domain.

Digital communication method and system

This invention is concerned with a transmission control method and apparatus in a collision interval for a collision of multidimensional hopping patterns. In the present invention, each orthogonal wireless resource in the coordinate of the multidimensional orthogonal resource can hop according to the hopping pattern negotiated between a transmitter and a receiver, and each corresponding channel is distinguished by the hopping pattern. A specific multidimensional hopping pattern is allocated to each secondary station. The hopping pattern is either permanently allocated to the secondary stations or temporarily allocated from the primary station during a call set-up. The permanent allocation of the hopping pattern to the secondary stations is achieved when the hopping pattern is identified based on a unique identifier, such as ESN of the secondary station. The hopping patterns of the secondary stations are mutually independent so that the coordinates of the same orthogonal resource is allocated to different secondary stations in a simultaneous manner in a specific moment. Through this invention, in order to improve the performance of the multidimensional resource hopping multiplexing system, refining transmission and perforation mechanisms for the collisions of multidimensional resource hopping patterns can reduce the overall perforation probability.

Queue-based active queue management process

ActiveUS20060045008A1More buffer capacityIncreasing queue sizeError preventionTransmission systemsNetwork communicationActive queue management
An active queue management (AQM) process for network communications equipment. The AQM process is queue based and involves applying at a queue size threshold congestion notification to communications packets in a queue of a link via packet dropping; and adjusting said queue size threshold on the basis of the congestion level. The AQM process releases more buffer capacity to accommodate more incoming packets by increasing said queue size threshold when congestion increases; and decreases buffer capacity by reducing said queue size threshold when congestion decreases. Network communications equipment includes a switch component for switching communications packets between input ports and output ports, packet queues for at least the output ports, and an active queue manager for applying congestion notification to communications packets in the queues for the output ports via packet dropping.

Detection of signatures in disordered message segments

A method of detecting signatures in message segments comprises employing a state machine for the detection of character strings in the message segments. The state machine executes for each input character a transition determined by a current state of the machine and a current input character. The message segments conform to TCP or other ordering transport protocol. The order of arrival of the message segments is monitored. In the event that an intermediate message segment is missing between a processed segment and an immediately subsequent message segment, the current state of said state machine at the end of the said processed segment is stored. The machine is restarted from its null or datum state for the examination of the immediately subsequent message segment, which is then temporarily stored. When the missing segment eventually arrives, it and the stored segment are successively examined for signatures by means of the state machine, beginning at the stored state. The invention allows for examination of overlapping signatures without requiring re-assembly of the segments or substantial buffering.

Nested LDPC encoders and decoder

An LDPC encoding system produces an encoded block by encoding the data as i data sub-blocks using an LDPC code H1, XOR'ing the H1 sub-block code words to generate a block code word and further encoding the block code word using an LDPC code H2 to produce p parity bits. The encoded block consists of a concatenation of the H1 code words and the p parity bits. To decode the encoded block, the system decodes each H1 sub-block code word and, if all of the H1 sub-block code words converge, the block has been successfully decoded. Otherwise, if one of the H1 code words fails to converge, the system performs an “extended” decoding operation in which the system produces a vector C by XOR'ing the i−1 properly decoded H1 sub-block code words. The system then combines the vector C with the sign values of the failed H1 sub-block code word, appends the parity bits and decodes the result as an H2 code word over the H2 LDPC code. For a next iteration, the system removes the vector C from the non-parity sign bits of the decoded H2 code word and provides the results along with the associated reliability information to an ISI detector for further decoding to produce an updated failed H1 code word. The updated H1 sub-block code word is then iteratively decoded as part of an H2 code word, and so forth, by combing and removing the vector C.
