RELIABLE DETECTION OF ERASE AND POWER CONTROL BASED ON ERASE FREQUENCY IN CLOSED CIRCUIT Russian patent published in 2009 - IPC H04L1/00 

FIELD: physics, communication.

SUBSTANCE: methods are described for detection of erase and power control for transmission without coding of errors detection. To detect erase, transmitter sends code words via channel of wireless communication. Receiver calculates metrics for every accepted code word, compares calculated metrics with threshold value of erase, and takes decision that received code word is "erased" or "non-erased". Receiver dynamically controls threshold value of erase on the basis of received available code words for achievement of target level of performance characteristic. For power control, internal circuit controls power of transmission for quality maintenance (SNR) of received signal at target level of SNR. External circuit controls target SNR on the basis of status of received code words (erased or non-erased) for achievement of target erase frequency. The third circuit controls threshold value of erase on the basis of status of received available code words ("good", "bad" or "erased") to achieve target conventional frequency of errors.

EFFECT: proper control of transmission power concerning transmissions, when coding is not used with detection of errors.
