Investigations of Bit Error Floors for Multi-Carrier Spread-Spectrum CDMA Systems with RAKE Receiver in Frequency-Selective Channels

چکیده
Abstract | In this paper, a multi-carrier spreadspectrum (MC-SS) code division multiple access (CDMA) system with RAKE receiver is investigated in a multi-user environment. The impact of the non-ideal MC-SS code signal autoand crosscorrelation properties on the system performance is examined. Terms for the probability of bit errors are derived considering these correlation behaviors. Furthermore, the performance of a MC-SS CDMA system is compared with those of a direct-sequence spreadspectrum (DS-SS) system based on GOLD sequences.

Frequency-domain Equalization for Antenna Diversity Reception of Ds-cdma Signals
A coherent rake combiner is employed as the channel matched filter in a DS-CDMA mobile radio. However, as the number of propagation paths increases, the coherent rake receiver incurs a serious degradation in the bit error rate (BER) performance due to severe inter-path interference (IPI). In this paper, frequency-domain equalization employed in multi-carrier code division multiple access (MC-CD...
متن کاملMulti-Carrier DS-CDMA Using Frequency Spread Coding
In this paper, a type of multi-carrier direct sequence code division multiple access (MC-DS-CDMA) system which uses frequency spread coding is proposed and investigated for the down-link. An MC-DS-CDMA system is a combined system of CDMA and multi-carrier modulation. This system is often categorized as a “serial to parallel (S/P) type” system because serial to parallel converted data symbols ar...

متن کاملMulticarrier CDMA with Adaptive Frequency Hopping for Mobile Radio Systems
A modified multicarrier (MC) direct-sequence code-division multiple-access (DS-CDMA) system has been proposed for use over slow multipath fading channels with frequency selectivity in the reverse link transmission of a cellular network. Instead of transmitting data substreams uniformly through sub-channels, data substreams hop over subchannels with the hopping patterns adaptively adjusted to th...
متن کاملBlind Adaptive Single-user Receivers for Ds-cdma Systems in Frequency-selective Fading Channels
| Linear minimum mean squared error (LMMSE) criterion can be used to obtain near-far resistant single-user receivers in direct-sequence code-division multiple-access (DS-CDMA) systems. A mod-iied version of the receiver, called LMMSE-RAKE receiver , has previously shown promising performance in frequency-selective fading channels. In this paper, both the convergence and BER performance of an ad...
