Introduction to CPM-OFDM: An Energy Efficient Multiple Access Transmission Scheme
نویسندگان
چکیده
In this paper we propose an energy efficient OFDM transmission scheme. Two CPM (continuous phase modulation) schemes are introduced to OFDM, keeping in view the constant envelope and continuous phase changing nature of CPM modulation. Energy efficiency of the proposed scheme is investigated by simulating PAPR (peak to average power ratio) and is compared with the conventional OFDM scheme. The impact of PAPR on BER is also investigated. BER (bit error rate) of the proposed scheme is simulated in different channels and is compared with conv-OFDM (QPSK-OFDM) scheme.

متن کاملEnergy Efficient Multiple Access Scheme for Multi-User MIMO-OFDM System with Improved Gain
In this paper, to improve the energy efficiency (EE) of multi-user multiple-input multiple-output (MIMO) orthogonal frequency-division multiple access (OFDMA) system, an Energy-efficient multiple access (EMA) scheme is proposed. It improves EE by selecting either time-division multiple access (TDMA) or space-division multiple access (SDMA) based on the no. of users or power consumption. Here, w...
متن کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
