Title:
RADIO DEVICE
Document Type and Number:
Japanese Patent JP3548162
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately search the reference point of an I-Q plane in a simple circuit constitution.
SOLUTION: A randomizing part 101 equalizes the numbers of 1 and 0 of data. An encoding part 102 encodes the data where the numbers of 1 and 0 are made equal. An HS-DSCH modulating/diffusing part 103 multi-level modulates the encoded data, and diffuses the data by using a diffusion code. Meanwhile, a commonly known signal is multi-level modulated, and then diffused by using the diffusion code by a CPICH modulating/diffusing part 104. The commonly known signal diffused by the CPICH modulating/diffusing part 104 and the data diffused by the HS-DSCH modulating/diffusing part 103 are multiplexed by a multiplexing part 105. The multiplexed transmission signal is transmitted from a radio transmitting part 106.
