【発明の名称】バースト信号発生装置
Document Type and Number:
Japanese Patent JP2971683
Kind Code:
B2
Abstract:
PURPOSE:To prevent a power leakage into an adjacent channel by extremely narrowing the frequency band width W of a burst signal k in a TDMA communication while a high turning on/off is held. CONSTITUTION:In an envelope adding part 19, an envelope processing to increase and decrease the amplitude data of each bit data of the top end part and trailing end part of base band data I and Q from which burst data e outputted from a bust data generating part 13 are separated is executed. Moreover, the conductive time TG of a high frequency switch circuit 23 which operates the turning on/off control of an orthogonal modulated signal i outputted from a frequency conversion circuit 22 is set to be equal to the continuing time Ts of the burst data e.
