“…The spectral shaping pulses can be ideally selected as the non-causal complementary Nyquist pulse pairs. Other practical (causal) pulses can be selected as long as proper equalization techniques (which will be presented separately [8]) are used in the receiver. After equalization, the received two parallel data streams are merged into one by parallel-to-serial conversion (P/S), followed by demapping and decoding to retrieve the output data bits.…”

The concept of complementary Nyquist pulse is introduced in this paper. Making use of a half rate Nyquist pulse and its complementary one, a dual pulse shaping transmission scheme is proposed, which achieves full Nyquist rate transmission with only a half of the sampling rate required by conventional Nyquist pulse shaping. This is essential for realizing high-speed digital communication systems with available and affordable data conversion devices. The condition for cross-symbol interference free transmission with the proposed dual pulse shaping is proved in theory, and two classes of ideal complementary Nyquist pulses are formulated assuming raised-cosine pulse shaping. Simulation results are also presented to demonstrate the improved spectral efficiency with dual pulse shaping and compare other system performance against conventional Nyquist pulse shaping.Index Terms-Nyquist pulse, complementary Nyquist pulse, high-speed digital communications, and data conversion devices.

“…This scheme allows two spectrally overlapped half‐symbol‐rate channels to be combined without ISI or CSI, achieving full‐rate transmission regardless of roll‐off factor. Furthermore, symbol‐rate based low‐complexity linear equalisation methods [20] for DPS transmission are proposed to reduce the required sampling rate of conventional fractionally spaced equalisation [21]. Without requiring any complicated equalisation algorithm, the DPS transmission scheme enables high‐speed communications in practical digital hardware.…”

Due to difficulties in manufacturing, data conversion devices with extremely high sampling rate are becoming the bottleneck in realising high‐speed communication systems with a large bandwidth. Dual pulse shaping (DPS) transmission allows half‐symbol‐rate conversion devices to be used for two parallel data streams to achieve full‐rate transmission, and is proved to be an effective solution. Here, two sets of ideal sinc‐function based complementary Nyquist pulses for DPS transmission are proposed. Theoretically, it is shown that the proposed pulses satisfy the inter‐symbol and cross‐symbol interference‐free conditions, and can achieve full‐Nyquist‐rate transmission with half of the sampling rate. With reference to commercially available D/As, two sets of practical dual spectral shaping pulses are further proposed, and the close relationship between the ideal and practical pulses are disclosed. Performance analysis for linear equalisation is provided in the presence of both timing offset between dual shaping pulses and carrier‐frequency offset. Two approaches are then proposed to improve the system robustness by adjusting the clock phase of the D/As and A/Ds. Simulation results are presented to provide a comparison between the proposed DPS transmission schemes and the state of the art, in terms of the performance metrics of peak‐to‐average power ratio and bit error rate.
