Title:
DEVICE AND METHOD FOR DETERMINING PULSE POSITION OF SIGNAL ENCODED BY PULSE MODULATION
Document Type and Number:
Japanese Patent JP3880339
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device and a method for determining the pulse position of a signal encoded by pulse modulation.
SOLUTION: In the device and the method for determining pulse position of signal encoded by pulse modulation, a signal can be received as a first component PCS and a second component DCS at least. A first storage unit 102 stores one symbol of the first component PCS at least and a second storage unit 104 stores one symbol of the second component DCS at least. A determination unit 118 is provided with a probability table 110 and when receiving the first and second components PCS and DCS, the address of this table is designated by at least one symbol of the first component PCS and at least one symbol of the second component DCS. Thus, the probability table 110 provides a value to be defined as a pulse position DDS.
