Abstract
Official abstract text for this publication.
A CFR estimation unit estimates channel frequency characteristic on the basis of a complex baseband signal provided by a front end via a data distribution unit, and a transmission symbol estimated value provided by a trellis decoder. On the basis of the channel frequency characteristics estimated in this manner, a carrier frequency control unit performs a carrier recovery control in order to become the carrier frequency error to zero in the front end, by performing an Auto Frequency Control based on changes in the channel phase in the full band of the frequency. As a result, carrier synchronization is performed appropriate for mobile receiving, and receiving performance is improved, even in the case of a digitally modulated signal having a DC pilot component by a single carrier.
First claim
Opening claim text (preview).
The invention claimed is: 1. A diversity reception device that receives a signal that has been digitally modulated by single carrier modulation, comprising: a plurality of branch processing units to each of which one of a plurality of received signals is individually inputted; a combination and equalization unit calculating an equalized signal from said plurality of received signals; and a transmitted symbol estimation unit calculating an estimated transmitted symbol from said…
