Summary:
The paper considers a wireless transmission system in a multiple-user environment. It involves a combination of Space-Time Trellis Coding (STTC) with Continuous-Phase Modulations (CPM) for multiple-antenna transmission (MIMO) in an uplink connection using the Frequency Division Multiple Access (FDMA) method. For a more efficient available band utilization, the distances between individual system user carriers are small. Such solution causes the deterioration of transmission quality due to the occurrence of Inter-Channel Interference (ICI). In order to reduce the bit error rate (BER), a combination of CPM and STTC has been used, along with a Minimum Mean Square Error (MMSE) MIMO detector and a low-complexity iterative algorithm for Inter-Carrier Interference (ICI) cancellation on the receiver side. BER results obtained in computer simulations are presented for proposed system.
