This study introduces a two-stage Time Difference of Arrival (TDoA) localization method using OFDM signals with carrier-phase measurements. Unlike conventional methods, our approach uniquely resolves ...

Ukraine war latest: Putin reveals one possible location for Trump talks - and reacts to idea of meeting Zelenskyy Vladimir Putin says he has nothing against meeting Volodymyr Zelenskyy - but also ...

The automatic signal modulation recognition of Orthogonal Frequency Division Multiplexing (OFDM) multi-carrier signals holds significant research importance and application value in areas such as ...

An OFDM symbol is a mixed-signal of multiple modulated subcarriers, which could be modulated by PSK and QAM. The OFDM transmitter transforms the bit-stream information into a sequence of PSK or QAM ...
