The outbreak of Covid-19 accelerated the practice of digital survival, and the "health code" launched based on the needs of epidemic prevention and control has become the representative of digital survival media, which is jointly built by science and technology enterprises and government departments. it has realized the full-state use in China, and accumulated long-term digital survival experience for the country, enterprises and individuals. At the same time, there are some media ethical problems in the use of Health Code, such as distinguishing users, leaking information, imprisoning the body and leading to the lack of subjects. In order to resolve the risk, we should re-examine the relationship between people and the media from the perspective of the subject, treat "health code" as a digital projection of personal health, and regain the service principle of digital technology. Humanize the "health code" and other digital media.

In this paper, a novel space-time-frequency code scheme - bit-interleaved space-time-frequency block coding (BI-STFBC) - being fit for OFDM system is considered for frequency-selective Rayleigh fading channels. Incorporating subcarrier grouping and choosing appropriate system parameters, we convert out system into a set of group STF (GSTF) system, within which STF coding is considered. Code bits are bit-wise interleaved across every grouping subcarrier before being grouped and mapped to space-time-frequency code, followed the unitary constellation-rotating precodes. The spectral efficiency and pairwise error probability (PEP) are also considered. Comparing with the existing alternatives, the proposed scheme can attain maximum diversity with low decoding flexibility. Simulation results confirmed the effectiveness of the proposed scheme.
