“…For large-scale wireless systems, how to safely and soundly deliver the data to the sink(s) -data persistence -is the essential and challenging tasks to solve [13]- [15]. Network modulation (NeMo) is firstly introduced in [15] which enhances successful data persistence by adopting an algebraic way to "combine" symbols which increases the information in a symbol while still guaranteeing the decodability at the sink.…”

“…Network modulation (NeMo) is firstly introduced in [15] which enhances successful data persistence by adopting an algebraic way to "combine" symbols which increases the information in a symbol while still guaranteeing the decodability at the sink. Then, NeMo method is applied to wireless communication systems, especially OFDM system which exploits multipath diversity with the aid of multiple subcarriers in order to enhance the error performance at the sink [16].…”

In this paper, we propose the new incremental relaying scheme using network modulation (NeMo) concept in OFDM-based systems. We first introduce how to integrate NeMo to OFDM incremental relay and show how both cooperative diversity and frequency diversity can be achieved on incremental relaying schemes. From the simulation results, it is confirmed that NeMo enables OFDM incremental relay to enjoy the frequencyselective diversity from grouping and subcarrier interleaving and to partially obtain the cooperative diversity gain for all the symbols, which is different from the conventional incremental relaying method. By increasing the NeMo modulator size, it is shown that the diversity gain is also increased causing the performance improvement in term of bit error rate.
