摘要： A transmission method of a digital broadcast, which is compatible with a DVB-T terrestrial digital broadcast system in Europe, saves a battery in a mobile terminal. Superframes in DVB-T are divided into units each including plural symbols so that an integer number of TS packets can be carried in each slot. At least one slot is used to transmit one service. Energy dispersion, Reed-Solomon coding, byte interleaving, convolutional coding, and time interleaving are applied to each service. When services for mobile terminal reception and services for fixed terminals are transmitted as the provided services, null packets may be transmitted before and after the slot carrying the mobile receiver service so that the fixed reception service and the mobile reception services are not mixed.

摘要： The disclosed method produces a spline-grooved cylindrical member, e.g. torque converter front cover, including a cylindrical portion having a target wall thickness t2, from a plate blank having a plate thickness t1. An outer peripheral portion of a disc-shaped blank is plastically deformed by pressing it against a mandrel with the concave peripheral edge of a thickness-increasing roller, so that a thick wall portion, of a thickness greater than the plate thickness t1 of the blank, is formed in the cylindrical portion. The thick wall portion is then pressed against the mandrel by forming rollers to form spline grooves therein. Thus, the other portions of the product have a wall thickness which is not unnecessarily increased. In this manner, the wall thickness t2 of the cylindrical portion is not entirely dictated by the wall thickness t1 of the blank material. Thus, a cylindrical member resistant to high pressures acting on its axially-extending outer cylindrical portion can be produced with an optimal configuration.

摘要： In fast Fourier transform, a necessary memory capacity is decreased, thereby decreasing a cost. The fast Fourier transform is performed on a symbol stored in a RAM by a butterfly operation unit in accordance with a RAM address generated by a RAM address generator. A RAM address conversion unit converts an input/output dummy address into an input/output real address by conducting bit reverse by a frequency specified in accordance with an input/output bit reverse signal, and converts a butterfly operation dummy address into a butterfly operation real address by conducting the bit reverse by a frequency specified in accordance with a butterfly operation bit reverse signal. In this manner, among output data of one symbol and input data of another symbol to be stored in the RAM subsequently to the output data of the one symbol, data having a common index indicating their orders in the symbols can be stored at the same address in the RAM. As a result, symbol input and symbol output can be overlapped.
摘要翻译：在快速傅里叶变换中，必要的存储容量减少，从而降低成本。根据由RAM地址发生器产生的RAM地址，通过蝶形运算单元对存储在RAM中的符号执行快速傅立叶变换。 RAM地址转换单元通过根据输入/输出位反向信号指定的频率进行位反转而将输入/输出虚拟地址转换为输入/输出实地址，并将蝶形运算虚拟地址转换为蝶形运算实际通过根据蝶形运算位反向信号指定的频率进行位反转。以这种方式，在随后的一个符号的输出数据之后的一个符号的输出数据和要存储在RAM中的另一个符号的输入数据之间，具有指示它们在符号中的顺序的公共索引的数据可以存储在相同的地址在RAM中。结果，符号输入和符号输出可以重叠。
