Transmission apparatus, reception apparatus and digital radio communication method

摘要

A transmission method includes generating first symbols for transmitting data, a signal point of each of the first symbols on an in-phase and quadrature-phase plane comprising an in-phase component and a quadrature-phase component and generating a second symbol, the second symbol being a pilot symbol. The method further includes selecting an insertion pattern of the second symbol, from a plurality of predetermined insertion patterns, inserting the second symbol in the first symbols based on the selected insertion pattern to generate a transmission signal, and transmitting the transmission signal. The first symbols are generated using a modulation scheme selected from a plurality of modulation schemes.

1. A transmission method comprising:
generating first symbols for transmitting data, a signal point of each of the first symbols on an in-phase and quadrature-phase plane comprising an in-phase component and a quadrature-phase component, a first symbol being a quadrature baseband signal; generating a second symbol, the second symbol being a pilot symbol and a second quadrature baseband signal; determining an interval of symbol insertion, outputting a signal indicating the determined interval, and selecting an insertion pattern of the second symbol, from a plurality of predetermined insertion patterns; inserting the second symbol in the first symbols based on the selected insertion pattern to generate a transmission signal; and transmitting the transmission signal, wherein the first symbols are generated using a modulation scheme selected from a plurality of modulation schemes.
