The digital broadcasting transmission device includes a randomizer which randomizes a dual transport stream including a normal stream and a robust stream, a supplementary reference signal inserter which inserts a certain supplementary reference signal into a stuffing region included in the randomized dual transport stream, a Reed-Solomon (RS) encoder which adds a parity into a parity region included in the dual transport stream, a robust processor which configures a new dual transport stream by convolution-encoding the robust stream among the dual transport stream, an interleaver which interleaves the configured dual transport stream, a trellis encoder which trellis-encode the interleaved dual transport stream, and a modulator which transmits the trellis-encoded dual transport stream. Accordingly, a sub-channel can be provided in which the robust data and the supplementary reference signal will be transmitted.

摘要： Disclosed is a digital broadcasting transmission/reception system having an improved reception performance and in a signal-processing method thereof. A digital broadcasting transmitter comprises a TS stream generator for inputting robust and normal packets having stuff bytes in predetermined positions and generating dual TS stream by inserting the robust packets between the normal packets; a randomizer for randomizing the dual TS stream; a stuff byte exchanger for replacing the stuff bytes of a randomized data streams from the randomizer to a predetermined known data; and an encoder for encoding a data streams to which the known data is inserted. Accordingly, the present invention detects the known data from a signal received from a reception side and uses the detected known data for synchronization and equalization, so that the digital broadcasting reception performance can be improved at poor multipath channels.

摘要： A magnetic resonance imaging (MRI) system includes a radio frequency (RF) coil which receives timing information about a pulse sequence and stores the timing information in a memory of the RF coil. Then, when an RF excitation signal is transmitted, the RF coil performs decoupling. When a magnetic resonance (MR) echo signal is generated, the RF coil receives the MR echo signal and transmits the MR echo signal to a central controlling apparatus through a wireless channel. When a transmission error arises, the RF coil retransmits corresponding data in an idle time when the RF excitation signal is not transmitted or the MR echo signal is not generated. Thus, the RF coil is prevented from being damaged by the RF excitation signal and prevents the quality of an MR image from deteriorating compared to a synchronization-type communication method.
摘要翻译：磁共振成像（MRI）系统包括射频（RF）线圈，其接收关于脉冲序列的定时信息，并将定时信息存储在RF线圈的存储器中。然后，当发射RF激励信号时，RF线圈进行解耦。当产生磁共振（MR）回波信号时，RF线圈接收MR回波信号，并通过无线信道将MR回波信号发送到中央控制装置。当发生传输错误时，RF线圈在没有发送RF激励信号或没有产生MR回波信号的空闲时间内重新发送对应的数据。因此，与同步型通信方法相比，防止RF线圈被RF激励信号损坏，并且防止MR图像的质量恶化。
