Generalized multicarrier DS-CDMA using various chip waveforms

چکیده
In this contribution the family of generalized multicarrier DS-CDMA (MC DS-CDMA) schemes [1] is investigated, when considering time-domain half-sine and raised-cosine chip waveforms, in addition to the rectangular chip waveform. Our results show that for a given subcarrier spacing the particular choice of the chip waveform has a substantial influence on the system’s performance. However, in the context of MC DS-CDMA using the optimum subcarrier spacing, all chip waveforms may provide a similar bit error rate (BER) performance.

In this letter, we extend our investigation of generalized multicarrier direct-sequence code-division multiple access by considering two additional types of chip waveforms, namely, the time-domain half-sine and raised-cosine chip waveforms, in addition to the rectangular chip waveform. A range of closed-form equations are provided for quantifying the effect of both the multipath interference an...

-In this paper, a multicarrier signalling technique is applied to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers instead of a single carrier. This type of signalling suppresses the narrowband interference & it is very robust to multipath fading without requiring the use of either a RAKE structure or an interference suppression...

Recently, multicarrier transmission schemes have been introduced into code-division multiple access (CDMA) systems to gain advantages for high data rate transmission. One of the methods is to transmit identical narrowband direct-sequence (DS) waveforms in parallel over a number of subchannels using frequency diversity. In this paper, we propose a multicarrier CDMA system with an adaptive subcha...
متن کاملPerformance assessment of MC-CDMA systems in impulsive noise
In this paper, we consider the effect of impulsive noise on the performance of multicarrier code division multiple access (MC-CDMA) systems and analyze the performance by examining the MC-CDMA system model in time domain. We have discovered that conventional Walsh-code based MC-CDMA is less robust to the presence of impulsive noise than the corresponding direct sequence (DS) CDMA and multicarri...
