Sentence examples for assisted channels from inspiring English sources

Glyn Evans, Socitm's president, said: "The influence of ICT continues to rise as more services are directly delivered through lower cost ICT assisted channels.

In this paper, we are proposing a near-optimum multiuser detector for STBC MC-CDMA transmission systems based on the Minimum Conditional Bit Error Rate (MCBER) and on Genetic Algorithm- (GA-) assisted channel estimation.

In a realistic scenario, the channel transfer function for the downlink has to be measured applying for example pilot assisted channel estimation (PACE) in a time division duplex (TDD) system, i.e., in the uplink each MSs transmits a sequence of M P pilot symbols d p = [ d p, 1, …, d p, M P ] T with d p H d p = M P which are known to the BS.

How much gain can be obtained by using redundancy of observations in time domain to assist channel decoding?

After precoding, N p equally-spaced pilot symbols are inserted in each slot to assist channel estimation at the receiver.

Fig. 1 An illustration of the components in CPSs How much gain can be obtained by using redundancy of observations in time domain to assist channel decoding?

In addition, we illustrate how much gain can be obtained by using the redundancy of system dynamics to assist channel decoding.

The idea of source coding (quantization) in the context of this work is combining the side information available at the controller to assist system state estimation, and the route of joint source and channel decoding in [20 25] is to utilize redundancy in the source to assist channel decoding.

One promising way to improve the performance of physical dynamics (or system state) estimation is the BP-based joint channel decoding and system state estimation algorithm, which we have already developed in [1] to utilize time-domain redundancy of system state to assist channel decoding.

The former can be used to evaluate the performance of system state estimation over multiple time slots, e.g., the gain by utilizing priori information from the previous time slot to assist channel decoding and state estimation at the current time slot.

As noted in Section 1, two objectives here are to evaluate how much gain can be obtained by utilizing π x(t−1),x t)(x(t−1)) to assist channel decoding and state estimation at time slot t and to evaluate the performance of state estimation over multiple time slots, i.e., the evolution of (mathbf {P}_{pi _{x},t-1}) as shown in Fig. 7(b).
