Abstract: A method of iterative detection and decoding by a receiver and a receiver for iterative detection and decoding. The method includes generating a channel estimated value using a received signal; storing the generated channel estimated value; generating a Log Likelihood Ratio (LLR) value using the received signal and the stored channel estimated value; and generating a decoded bit as feedback information using the LLR value, wherein the LLR value is iteratively regenerated using the generated feedback information, the stored channel estimated value, and the received signal.

Abstract: Methods and apparatuses are provided for performing a cell search by a receiver in a communication system. A scrambling code is identified by correlating a common pilot channel with a first synchronization accumulation length based on a frame boundary and a code group. A multipath signal is sought by correlating the common pilot channel with a second synchronization accumulation length based on the frame boundary and the code group. A difference between, or a ratio of, a first maximum value of first correlation values acquired during identification of the scrambling code and a second maximum value of second correlation values acquired during searching for the multipath signal, is determined. It is determined whether a frequency offset exists by comparing the difference or the ratio with a predetermined threshold value. The frequency offset is estimated and the frequency offset is transmitted to a demodulator, when the frequency offset exists.

Abstract: Methods and apparatuses are provided for reducing power consumption by early decoding. It is determined whether a predetermined decoding condition is satisfied upon expiration of a time unit in a transmission time interval. Decoding is performed on a signal that has been received through the time unit in the transmission time interval, when the predetermined decoding condition is satisfied. A controller outputs an instruction signal to a RF processor to set to a low-power mode during a remaining time period of the transmission time interval after the time unit in the transmission time interval, when the decoding is successful. Decoding is performed on the signal that has been received through the RF processor upon expiration of a last time unit of the transmission time interval regardless of the predetermined decoding condition, when the time unit is the last time unit in the transmission time interval.

Abstract: Methods and apparatuses are provided for controlling a communication device. A first subframe is received from a serving cell and a plurality of subframes is received from a plurality of neighbor cells. A respective time difference of arrival (TDOA) is measured for each of the plurality of subframes based on a time of arrival (TOA) of the first subframe. At least one of the measured TDOAs is transmitted to a location server. The respective TDOAs are measured based on at least one of a cell-specific reference signal (CRS) and a synchronization signal in the plurality of subframes.
