th generation mobile radio systems.
The combination of multiple antennas and multi-carrier code division multiple-access (MC-CDMA) is a strong candidate for the downlink of the next generation mobile communications. The study of such systems in scenarios that model real-life transmissions is an additional step towards an optimized achievement. We consider a realistic MIMO channel with two or… (More)
We compare the performance of Alamouti's space-time block coded MC-CDMA systems for indoor and outdoor realistic scenarios with zero forcing or minimum mean square error detection schemes. Two different configurations of the system are considered for the two scenarios. The different results obtained as well for indoor as for outdoor scenarios demonstrate… (More)
In this paper multiuser detection techniques, such as Parallel and Serial Interference Cancellations (PIC & SIC), General Minimum Mean Square Error (GMMSE) and polynomial MMSE, for the downlink of a broadband Multi-Carrier Code Division Multiple Access (MC-CDMA) system are investigated. The Bit Error Rate (BER) and Frame Error Rate (FER) results are… (More)
I. INTRODUCTION Orthogonal frequency division multiplexing (OFDM)  is a suitable technique for broadband transmission over multipath fading radio channels achieving high data rates. In addition to the coherent OFDM modulation, spreading in frequency or time direction is introduced for multi-carrier code division multiple access (MC-CDMA). MC-CDMA is a… (More)
