soft technique of decision
解釋
決策軟技術-
However, to the essential of communication technology, those techniques are all change in transmission medium or channel. recently, because of the development of dsp, ifft / fft, 46 / 128 / 256qam using in high - speed modem, and gradual introduction of new coding technique, soft decision technique, channel self - adapting, guard interval, ofdm ( orthogonal frequency division multiplexing ) arouse more and more attention. as a technology of high - speed transmission, ofdm can resist isi effectively
近年來,隨著dsp晶元技術的發展,傅立葉變換反變換、高速modem採用的64 128 256qam技術、柵格編碼技術、軟判決技術、通道自適應技術、插入保護時段、減少均衡計算量等成熟技術的逐步引入,正交頻分復用ofdm ( orthogonalfrequencydivisionmultiplexing )作為一種可以有效對抗信號波形間干擾的高速傳輸技術,引起了廣泛關注。
