Bit division multiplexing
WebBut, DWT-OFDM highly suffered due to downsampling, which degrades system efficiency. To overcome this, a redundant discrete wavelet transform (RDWT) is proposed in this article to enhance spectral efficiency. For modulation, 16-bit quadrature amplitude modulation (QAM) is introduced in this work. WebDec 11, 2015 · Multipexing merupakan sebuah teknik yang bekerja di physical layer pada lapisan OSI. Tujuan : Tujuan utamanya adalah untuk menghemat jumlah saluran fisik misalnya kabel, pemancar & penerima (transceiver), atau kabel optic. Selain itu multiplexing juga bertujuan untuk meningkatkan effisiensi penggunaan bandwidth / …

WebJan 16, 2014 · More precisely, we consider the following strategies: time sharing, hierarchical modulation and bit division multiplexing. Our main contribution is the combination of bit division multiplexing with non-uniform QAM to improve the performance of broadcasting systems. WebCode-division multiple access ( CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth ).
