MIMO-OFDM Channel Estimation Using Pilot Carries
Kala Praveen Bagadi,Susmita Das +1 more
TL;DR: Channel state information for both single-input single-output (SISO) and MIMO systems based on pilot aided arrangement is investigated and MMSE estimation has been shown to perform much better than LS but is more complex than LS for the MIMo system using pilot carriers.
Proceedings ArticleDOI
Modelling of IoT Traffic and Its Impact on LoRaWAN
TL;DR: This paper considers modelling the traffic from IoT devices connected through LPWAN technologies using the CMMPP model to represent characteristic traffic from independent IoT devices triggered by an event and demonstrates that there is a significant performance hit in LoRaWAN based networks, during the occurrence of events.
Journal ArticleDOI
Recent trends in multiuser detection techniques for SDMA-OFDM communication system
TL;DR: Various MUD techniques for SDMA-OFDM system are reviewed, which can provide high spectral efficiency and resistance from inter symbol interference and multiple users transmit their data simultaneously.
Journal ArticleDOI
Neural network-based adaptive multiuser detection schemes in SDMA–OFDM system for wireless application
Kala Praveen Bagadi,Susmita Das +1 more
TL;DR: MUD using NN models outperforms other existing schemes like genetic algorithm--assisted minimum bit error rate (MBER) and minimum mean square error MUDs in terms of BER performance and convergence speed.
Journal ArticleDOI
Efficient complex radial basis function model for multiuser detection in a space division multiple access/multiple-input multiple-output-orthogonal frequency division multiplexing system
Kala Praveen Bagadi,Susmita Das +1 more
TL;DR: An adaptive multiuser detection (MUD) technique using the complex radial basis function (CRBF) network is proposed for space division multiple access-orthogonal frequency division multiplexing (SDMA-OFDM) system and has low complexity, better performance compared with MSER MUD and also supports overload scenario.
