Abstract
The present invention provides a narrowband OFDM (NOFDM) system with frequency diversity redundant transmission and receiver diversity selection and combining scheme. The communication channel is segmented into independent plurality of sub-channels. The sub-channels can be used in an aggregated mode to transmit different data on every sub-channel or in a number of redundant modes, where the same data is sent on multiple sub-channels to achieve maximum robustness of communication. Redundant modes may include channel selection diversity and/or weighted channel combining diversity.
