An ${N}$ -continuous generalized frequency division multiplexing (GFDM) transceiver architecture is studied with the objective of striking a balanced trade-off between the bit error rate (BER) and the sidelobe suppression performance. More specifically, in the proposed ${N}$ -continuous GFDM signaling, the basis signals constructed allow one to make the GFDM signal ${N}$ -continuous and attain a compact spectrum as an explicit benefit of sidelobe suppression. We further reveal that compared to conventional ${N}$ -continuous orthogonal frequency division multiplexing (NC-OFDM), ${N}$ -continuous GFDM introduces relatively low interference through evaluating the signal-to-interference ratio (SIR). Secondly, a signal recovery algorithm is presented by constructing a recovery matrix to eliminate the interference. Finally, it is demonstrated that the proposed ${N}$ -continuous GFDM scheme outperforms its ${N}$ -continuous OFDM counterpart in terms of sidelobe suppression, while achieving moderate BER performance degradation as opposed to original OFDM.

GFDM 的 N 连续信令

研究了 ${N}$ - 连续广义频分复用 (GFDM) 收发器架构，目的是在误码率 (BER) 和旁瓣抑制性能之间取得平衡。更具体地，在提议的${N}$ -连续GFDM信令中，构建的基础信号允许使GFDM信号${N}$ -连续并且获得紧凑频谱作为旁瓣抑制的显着益处。我们进一步揭示，与传统的 ${N}$ - 连续正交频分复用 (NC-OFDM) 相比，${N}$ - 连续 GFDM 通过评估信号干扰比 (SIR) 引入了相对较低的干扰。其次，提出了一种通过构建恢复矩阵来消除干扰的信号恢复算法。最后，
