Title:
マルチ・キャリア信号のガード間隔を使用したチャネル推定
Document Type and Number:
Japanese Patent JP4125722
Kind Code:
B2
Abstract:
The method involves generating bit streams and corresponding sets of frequency domain carrier amplitudes X 0(K) to XN(k), where k is orthogonal frequency division multiplexing (OFDM) symbol number, modulated as OFDM symbols. The vector of specific size that are deterministic and known to receiver and transmitter, are inserted as guard intervals in sample streams, and OFDM symbols are transmitted from transmitter to receiver. Independent claims are also included for the following: (1) transmitter; and (2) receiver.
