FFT implementable CS-CDMA and its performance under polar clipping noise
This paper proposes the use of convolutional spreading code-division multiple access (CS-CDMA) with Z-connectable complete complementary code. We present simple implementation structure based on fast Fourier transform (FFT) and discuss the trade-off relationship between its computational complexity...

Zusammenfassung: | This paper proposes the use of convolutional spreading code-division multiple access (CS-CDMA) with Z-connectable complete complementary code. We present simple implementation structure based on fast Fourier transform (FFT) and discuss the trade-off relationship between its computational complexity and clipping resistance. Simulation results indicate that the proposed system can mitigate the demand for linear amplifier at the expenses of implementation complexity. |
