    Abstract: An apparatus and method for generating a Channel Quality Indicator (CQI) in a wireless communication system are provided. The method includes receiving a Modulation and Coding Scheme (MCS) index and resource allocation information of a traffic channel and calculating a spectral efficiency at a particular time point, determining a temporary CQI index having a spectral efficiency closest to the calculated spectral efficiency in an index set, reading a CQI metric a time τ before the particular time point, determining, if the temporary CQI index is reported at the particular time point, an error rate based on the CQI metric, the error rate being a probability of an error occurring in a traffic channel after the time τ, receiving an error check result of the traffic channel transmitted at the particular time point and calculating a new error rate by applying a weight to the error check result and the error rate, and determining a CQI index to be fed back to a transmitter using the new error rate. Hence, the CQI index which maximizes spectral efficiency is determined and a Physical Downlink Shared CHannel (PDSCH) acknowledgement (ACK)/negative acknowledgement (NACK) probability is directly estimated adaptively according to a change in channel, thereby providing useful performance in various channel environments.

    Abstract: An electrical fuse includes first and second active regions doped with respective first-type and second-type impurities that form a horizontal P/N junction, first and second spaced apart silicide layers on respective portions of the top surfaces of the first and second active regions, and first and second contacts on the respective top surfaces of the first and second silicide layers. When a first reverse voltage that is higher than a threshold voltage is applied to the electrical fuse through the first and second contacts, the P/N junction is broken down by a reverse current flowing between the first and second active regions so that the electrical fuse is rendered conductive in response to a second reverse voltage that is less than the threshold voltage.
