Narrow-band interference suppression in wavelet packets based multicarrier multicode CDMA overlay system
The wavelet packets based multicarrier (MC) multicode (MCD) code-division multiple-access (CDMA) transceiver consists of the MCD part, which ensures the transmission for high speed and flexible data rate; the MC part contributing to robustness to frequency-selective fading and flexibility for handling multiple data rates; and wavelet packets (WPs) modulation technique, which contributes to the ...
متن کاملEffect of Diversity and Filtering on the Performance of Wavelet Packets Base Multicarrier Multicode CDMA System
In Wavelet Packets Based Multicarrier Multicode CDMA system, the multicode (MCD) part ensures the transmission for high speed and flexible data rate, the multicarrier (MC) part ensures the flexibility of handling multiple data rates, and wavelet packets modulation technique contributes to the mitigation of the interference problems. The CDMA system can suppress a given amount of interference. I...
متن کاملPERFORMANCE OF MULTIBAND COMPLEX WAVELET BASED MULTICARRIER DS-CDMA SYSTEM WITH MULTI-ANTENNA RECEIVER OVER NAKAGAMI-m FADING CHANNEL
On the basis of analyzing the principle of multicarrier DS-CDMA, we propose a novel multiband complex wavelet based multicarrier DS-CDMA system in this paper by using the optimized multiband complex wavelet as multicarrier basis function. The system bit error rate (BER) performance is investigated over Nakagamim fading channel. Without any cyclic prefix (CP), the proposed system can avoid the d...
متن کاملPerformance of Coded Modulation in Multicarrier CDMA System
Coded modulation scheme introduce robust and reliable system. It combine coding and modulation in one system. This paper show performance of coded modulation with coding rate 2/3, using 8PSK and convolutional coding that implemented in MC CDMA system. MC CDMA is one of multicarrier system that combine OFDM and CDMA so its offer reliable system in frequency selective fading. Decoding process for...
متن کاملMulticarrier DS/SFH-CDMA systems
In this paper, multicarrier direct-sequence/slow-frequency-hopping (MC DS/SFH) code-division multiple-access (CDMA) systems are proposed, in which multiple carriers are modulated by the same DS waveform and hopped in frequency according to a random hopping pattern. The receiver dehops the received signal with the same pattern, provides RAKE receivers for each carrier, and combines the outputs w...
