Sentence examples for error and feedback from inspiring English sources

However, it is impossible to obtain perfect channel information at the transmitter due to channel estimation error and feedback delay.

Because of channel estimation error and feedback delay, the CSI existing at both transmit and receive side will be imperfect.

In [8], the authors studied upper and lower bounds on the achievable sum-rate of a correlated/uncorrelated MU-MIMO channel with channel estimation error and feedback delay.

Because of the linear relation between the phase error and feedback control signal, the sawtooth reference signal is able to obtain a better stability.

Therefore, it is highly desirable to consider both CSI estimation error and feedback delay when designing the MIMO AF relay system.

However, due to estimation error and feedback delay, there is usually certain mismatch between the estimated and the real channel matrices in practice.

CSIT is always got through feedback from the MSs in the FDD systems and through uplink channel estimation based on uplink-downlink reciprocity in the TDD systems, so the main sources of CSIT imperfection come from channel estimation error, delay and feedback error [15 17].

Some of the annotations commonly used include skills associations, identification of common errors and feedback prompts.

However, perfect channel gain is extremely difficult to obtain due to estimation errors, quantization errors, and feedback delays.

There are three key questions that we would like to address in this section: · What is the positioning system precision, including systematic errors and feedback system resolution?

Analysis of the adaptive feedback system indicates that the conventionally interpreted plant estimation error can be arbitrarily small yet induce algorithm divergence; while other cases may have very large estimation errors and feedback loops cause controller instability.
