摘要： PROBLEM TO BE SOLVED: To provide a multipath equalization apparatus and a multipath equalization switching method to maintain a signal characteristic which does not apply multipath equalization processing and output the same, in switching by a switch whether or not multipath equalization processing is applied to a received signal. SOLUTION: A switch controller 15 outputs a "0" signal to a selection portion 127 in a multipath equalizer 12 after the switch 14 is switched so as to derive a by-pass signal. An IF signal output from the multipath equalizer 12 becomes zero thereby while the switch 14 is switched so as to derive the by-pass signal. That is, even when isolation of the switch 14 is not good, no signal from the multipath equalizer 12 leaks to the by-pass signal output to a post-stage. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：为了提供一种多路径均衡装置和多路径均衡切换方法，以维持不应用多路径均衡处理的信号特性并输出相同的信号，在通过开关的切换中是否应用多路径均衡处理到接收信号。解决方案：开关控制器15在切换开关14之后，向多路径均衡器12中的选择部分127输出“0”信号，以导出旁路信号。从多径均衡器12输出的IF信号变为零，由此开关14被切换以导出旁路信号。也就是说，即使当开关14的隔离不良时，来自多路径均衡器12的信号也不会泄漏到后级的旁路信号。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a digital broadcast receiving device, capable of more accurately compensating the transmission line distortions by performing symbol determination on a broadcast signal with high accuracy, even under an environment where the broadcast signal is influenced by transmission line distortions, such as, phasing.
SOLUTION: A symbol determining unit 19 performs a symbol determination on composte signals from a composition unit 17. In such a case, complex baseband digital signals for which compensation units 16-1 to 16-n have compensated for transmission line distortion, are selected by a selection unit 18 and outputted to the symbol determining unit 19. In symbol determination, if symbol termination cannot be performed using only the composte signals, the complex baseband digital signals, outputted from the selection unit 18, are then referred to, and the symbol determination is performed based on a majority decision of the composte signals and the complex baseband digital signals.

摘要： PROBLEM TO BE SOLVED: To improve a quality of a receiving signal by controlling a wraparound component to a receiving side by a transmission signal in a repeating transmission by a MFN.
SOLUTION: A weight generating portion 13 calculates a weight value for offsetting a wraparound component in units of transmission signal based on a signal of each of a plurality of frequency channels divided by a channel dividing portion 5. A broadcast wave repeating installation delays each transmission signal allocated by a transmission channel by a delay circuit 11 in a channel re-arranging portion 7 and generates the wraparound component by multiplying each delayed transmission signal by the weight value. The wraparound component generated for each transmission signal is analog-converted through a D/A converter 15 and is supplied to a subtractor 2 after being combined by a second channel combining portion 14. The subtractor 2 offsets the wraparound component from the transmission signal converted into an IF band by a down converter 1 and inputs it in a variable gain amplifier 3.
