Abstract :
The bit error rate of a multiple-input multiple-output (MIMO) multi-carrier code division multiple access (MC-CDMA) communication system has been estimated through Monte Carlo simulation. Cyclically rotated complete complementary codes (CRCCCs) were employed in a code reuse scheme along with orthogonal space-time block codes (OSTBCs) and orthogonal frequency division multiplexing (OFDM). This scheme achieves transmit diversity as well as secondary multipath (frequency) diversity. The technique combines three powerful technologies with low complexity decoding that relies primarily on the fast Fourier transform (FFT) algorithm. This work provides a method for implementation in scenarios where computational and power resources are limited.
