Abstract:
The paper considers a wireless transmission system in a multiple-user environment that can support slicing networks. It involves a combination of non-binary convolutional codes and Space Time Block Codes (STBC) technique with narrowband Continuous-Phase Modulation (CPM) for transmission in an uplink channel using the Frequency Division Multiple Access (FDMA) method. Energy efficiency signals, e.g., Continuous Phase Modulation could be used for transmission managing or feedback information signals in return channels of slicing networks. We analyse performance of a transmission in such return channels which apply FDMA method with coded CPM signals via computer simulations. In order to reduce the Bit Error Rate (BER) a concatenation of CPM with non-binary convolutional codes over ring and STBC technique has been used. The spectral efficiency of investigated system is improved by reducing the inter-carrier frequency spacing and using a low-complexity iterative algorithm for Inter-Carrier Interference (ICI) cancellation at the receiver. BER results obtained in computer simulations are presented for the proposed solution. The results suggest that FDMA coded STBC-CPM transmission might constitute a desirable option for return channels in slicing networks.
