Mimo signal processing method involving a rank-adaptive matching of the transmission rate
InactiveUS20060193294A1Reduce complexityReliable data transmissionPower managementTransmission control/equalisingData streamTransmitted power
A bidirectional signal processing method uses parallel transmission of digital transmitted data streams in a multiple input-multiple output system. Related art methods generate high bit error rates mostly in singular transmission channels. For this reason, the rank-adaptive signal processing method provides that the number nd of active subchannels are varied according to the actual channel behavior in order to effect a robust data transmission even in singular radio channels based on a transmit-side and receive-side channel knowledge and a modification of the data vector by a linear matrix vector multiplication while introducing a factor gamma for limiting the maximum transmit power. The maximum transmit power is then only distributed to the currently activated subchannels so that no transmit power remains unused. Another optimization of the number of subchannels nd occurs when selecting the modulation and encoding methods. During the optimal rank-adaptation according to the water-filling principle, another power is allocated to each subchannel. Another modulation and encoding method is accordingly selected for each data stream. During the suboptimal rank-adaptation according to the channel inversion principle, all subchannels have the same power whereby enabling the data streams to be modulated and encoded in a common source

ActiveCN110213115AImprove stabilityReduce the number of transfersData switching networksLyapunov stabilityEvent trigger
The invention provides a security control method of an event-driven network control system under a multi-network attack. Considering the network transmission security problem, a random network spoofing attack, a replay attack and a DoS attack are sequentially introduced, and a system closed-loop model under the multi-network attack is established. Further considering the constraint of the limitednetwork bandwidth, an event trigger mechanism is introduced to screen and release sampling data meeting a preset event trigger condition to the network for transmission, thereby establishing a new switching system model on the basis of the system closed-loop model. Based on a switching system model, a Lyapunov stability theory is utilized to obtain a sufficiency condition for enabling the system to meet the stability of a mean square index, and a group of linear matrix inequalities is solved to obtain the gain of the state feedback controller. Compared with an existing controller design method, safe and stable operation of the network control system under the influence of multi-network attacks is guaranteed, meanwhile, the data transmission frequency is reduced, and limited network bandwidth resources are saved.

A source signal transmitted through multiple channels having space, time and frequency diversities to generate multiple received signals is recovered by an iterative associative memory model with dynamic maximum likelihood estimation. A current symbol vector representing the multiple received signals is projected to a net-vector using a linear matrix operation with a weight matrix W. The weight matrix is obtained by a singular value decomposition of an input symbol sequence. The net-vector is mapped to a nearest symbol vector using a non-linear operation with an activation function. The projecting and mapping steps are repeated until the nearest symbol vector converges to a valid symbol vector representing the source signal.

The invention discloses a channel estimation method for an orthogonal frequency division multiplexing (OFDM) system under an interference environment. A column singular matrix is multiplied by a corresponding orthogonal projection matrix to obtain a zero matrix so that the vector obtained in the step (5) is equivalent to T=QIp, wherein the element Ip (k) in the vector Ip is a result of dividing an interference signal and noise by a local pilot signal. Because the orthogonal projection matrix is a linear matrix, the statistical property of each element T (k) of the vector T is the same as thatof the element Ip (k), the variance estimation value obtained in the step (5) is the sum of the interference signal variance and the noise variance, and optimal estimation of channel time domain impulse response is obtained by using the step (7). The method has low calculation complexity, and the estimated performance of the method is approximate to the ideal channel estimated performance in the absence of interference signals; and meanwhile, aiming at block pilot patterns and uniformly-spaced comb pilot patterns, the method is insensitive to the power of the interference signal, only needs one OFDM symbol, and has good instantaneity.
