受信装置および受信方法

Document Type and Number:

Japanese Patent JP7389169

Kind Code:

B2

Abstract:

A transmission device that improves data reception quality includes: a weighting synthesizer (203) that generates a first precoded signal and a second precoded signal; a first pilot inserter (207A) that inserts a pilot signal into the first precoded signal; a phase changer (205B) that applies a phase change of i × Δλ to the second precoded signal, where i is a symbol number and an integer that is greater than or equal to 0; an inserter (207B) that inserts a pilot signal into the phase-changed second precoded signal; and a phase changer (209B) that applies a phase change to the phase-changed and pilot-signal-inserted second precoded signal. Δλ satisfies π/2 radians <Δλ <π radians or π radians <Δλ < 3π/2 radians.
