Emmanuel believed the Italians were unfit for parliamentary government and understood only rule "by bayonets and bribery". Only Giuseppe Garibaldi escapes revisionism.

Nevertheless, behind Gilmour's argument lie some peculiar assumptions about nationalism. He argues that the Italian nation never existed before the 19th century, and even then it was imposed on its subjects for all the wrong reasons. But all modern nation states lay claim to their antique roots, and their popular support is always questionable. Is Italy really any different?

Gilmour has no time for Marxist explanations of the pitfalls of nationalism, but he somewhat oddly ends up endorsing a similarly old-fashioned celebration of the local and the parochial. Perhaps the book responds to a deeper disquiet with the limitations of the European nation state, at a time whenIn a wireless communication system, a receiving end and a transmission end usually employ space division multiplexing in a multi-antenna system to obtain a higher transmission rate. In order to realize space division multiplexing, the transmission end usually maps a data layer to be transmitted to an antenna port by utilizing precoding, thus obtaining high transmission performance. In order to realize the precoding on the transmission end, the transmission end needs to know all or a part of the channel state information. In a Time Division Duplexing (TDD) system, a transmission end may obtain the channel state information via the reciprocity of uplink and downlink channels; and in a Frequency Division Duplex (FDD) system, the receiving end usually needs to notify the transmission end of the channel state
