Abstract: A digital television (DTV) transmitter and a method of coding data in the DTV transmitter method are disclosed. A pre-processor pre-processes the enhanced data by coding the enhanced data for forward error correction (FEC) and expanding the FEC-coded enhanced data. A data formatter generates one or more groups of enhanced data packets, each enhanced data packet including the pre-processed enhanced data. And, a packet multiplexer generates at least one burst of enhanced data by multiplexing the one or more groups of enhanced data packets. Herein, each burst of enhanced data includes at least one group of enhanced data packets. The DTV transmitter may further include a scheduler which generates first and second control signals to control operations of the data formatter and the packet multiplexer, respectively.

Abstract: A scroll compressor is provided, in which at least one bypass hole that bypass a portion of a refrigerant before the refrigerant is discharged through a discharge hole is formed at a position where a bypass section that bypasses the refrigerant through the at least one bypass hole overlaps a discharge section that discharges the refrigerant through the discharge hole. The at least one bypass hole is formed at a position where a wrap volume ratio (Vs/Vd), which is a ratio of a suction volume (Vs) with respect to a discharge volume (Vd) in a compression chamber, is within the range of about 1.8˜2.2. With this configuration, over-compression of refrigerant may be prevented in a low speed driving mode, and efficiency of the compressor may be enhanced in the low speed driving mode and under a low load condition.

Abstract: A method and terminal apparatus are described for performing channel interleaving at a terminal in a multiple-input multiple-output (MIMO) wireless communication system. A number of columns C of an interleaver matrix are assigned as a number of symbols for transmitting data per subframe (Nsymb). A number of rows R of the interleaver matrix is defined as H · L · log 2 ? Q C , where H is a number of modulation symbols per layer, L is a number of layers and Q is a modulation order. Input vector sequences are written into entries of the interleaver matrix, row by row. Each of the entries has a size of L·log2 Q bits. Output bit sequences are generated by reading out the entries of the interleaver matrix, column by column. The output bit sequences are modulated by a unit of log2 Q bits, to generate modulation symbols. The modulation symbols are mapped to the L layers, and transmitted by using the L layers.
