    摘要: An optimum I/Q imbalance compensating apparatus and method in a zero-IF OFDM receiver. In the apparatus, a first compensator generates a first symbol by removing interference from a second distorted symbol on an (Ns−m+1)th subcarrier from a first distorted symbol on an mth subcarrier by a first compensation coefficient in an OFDM FFT signal of Ns subcarriers. A first hard decider generates a first compensated symbol by hard-decision on the first symbol, an error calculator generates an error symbol by subtracting the first received symbol from the first compensated symbol. A second compensator generates a second symbol by eliminating interference from the first distorted symbol from the second distorted symbol using a second compensation coefficient. A second hard decider generates a second compensated symbol by hard-decision on the second symbol, and an adaptive controller updates the first compensation coefficient using the error symbol and the second compensation symbol.

    摘要: A gap filler apparatus providing cyclic delay diversity in a digital multimedia broadcasting (DMB) system. In the gap filler apparatus, a receiver receives an orthogonal frequency division multiplexing (OFDM) signal transmitted as a broadcasting signal. A symbol synchronization unit acquires symbol synchronization of the OFDM signal, detects a guard interval of an OFDM symbol using the symbol synchronization, determines a sample length, by which the OFDM symbol is cyclic-delayed within the guard interval, and cyclic-delays the OFDM signal by the determined sample length. An amplifier amplifies the cyclic-delayed OFDM signal. A transmitter transmits the amplified OFDM signal to a wireless network.

    摘要: A device for linearizing a transmitter in a digital radio communication system. In the device, a predistortion lookup table stores predistortion data determined by measuring in advance distortion characteristics of the transmitter with respect to input baseband data. During transmission, the device synthesizes the input baseband data with the predistortion data to predistort the input data so as to compensate for the distortion characteristics caused by non-linear elements constituting the transmitter.

    摘要: A method and apparatus for synchronization of a moving picture experts group (MPEG) transport stream, which minimizes an initial delay are provided. A packet synchronization unit and a mode of the packet synchronization unit to are initialized to “0”. Values of sync words are stored by shifting values of a sync word register when the sync words have been received and the received sync word is compared with predetermined code words As a result of the comparison, a determination is made as to whether a bit difference between the sync words and the predetermined code words exceeds a predetermined threshold value. A verification is then made as to whether all bits of the sync words correspond to all bits of the predetermined code words, when it is determined as a result of the determination that the bit difference is less than or equal to the predetermined threshold value and the MPEG transport stream is descrambled before returning to step of storing values of sync words by shifting values of a sync word register.

    摘要: Disclosed are an apparatus and a method for decreasing a channel change time in a digital broadcasting reception terminal. Starting time information of at least one non-reference channel is selected. When the user selects a non-reference channel, broadcast data thereof is received by using the collected starting time information. The apparatus extracts time offset values between a starting time of a current reference channel and that of each at least one non-reference channel, and then obtains the starting time of each non-reference channel by using the extracted time offset values. When a channel change is performed, the starting time of the non-reference channel is established to receive broadcast data based on the starting time according to a corresponding time offset value. Hence, a time period required for a channel change is significantly reduced.
