This paper investigates serially concatenated (SC) and interleaved transmission schemes for a new class of continuous phase modulation (CPM), which has the property being a single sideband (SSB). This new CPM is commonly called Single Side-Band Frequency Shift Keying (SSB-FSK). Due to the ample space of SSB-FSK parameters, finding good serially concatenated schemes using SSB-FSK with desired spectral and energy efficiencies as well as reasonable complexity, is challenging. We present a systematic, simulation-based extrinsic information transfer (EXIT) chart approach to evaluate this multi-objective problem (improve spectral and energy efficiencies and reduce complexity) and subsequently design a competitive serially concatenated SSB-FSK based scheme. We show that iterative decoding of SC schemes using SSB-FSK (SC-SSB-FSK) provides close to optimal performance. Furthermore, the bit error rate (BER) of SC-SSB-FSK is compared to that using raised cosine (RC) based CPM signals. It has been shown that the proposed technique outperforms the state-of-the-art serially concatenated systems. |
