A good example can be observed among European network operators for the prices to pay for frequency bands for UMTS/IMT2000. Keeping this in mind, the fIrst goal when designing future wireless communication systems has to be the increase in spectral effIciency by allowing higher flexibility for the system design and deployment. The development in digital communications in the past years has enabled effIcient modulation and coding techniques for robust and spectral effIcient data, speech, audio and video transmission. Here, we should mention two interesting and successful techniques. These are the multi-carrier modulation (e. g. OFDM) and the spread spectrum technique (e. g. DS-CDMA). During the last decade of this millennium the technique of multi-carrier transmission for wireless broadband multimedia applications has received wide interest. Its fIrst great success was in | | 出版日期 | Book 2002 | | 关键词 | Demodulation; Modulation; Ping; Potential; Signal; communication; communication system; development; filter; | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4757-3569-7 | | isbn_softcover | 978-1-4419-4945-5 | | isbn_ebook | 978-1-4757-3569-7 | | copyright | Springer Science+Business Media New York 2002 |
