摘要： The differences among the propagation delays, at the antennas of receivers, of the received signals received through the receivers are accurately reproduced by a small-scale circuit. A frequency data creating section (6) supplies frequency data including mutually synchronized frequency components to receivers (2-1 to 2-n). A local signal generating section (3-n), represented by a D/A converter, of the receiver (2-n) generates a local oscillation signal from the frequency data. Therefore the pass phase of the received signal outputted from the antenna (1-n) through the receiver (2-n) is fixed. As a result, the differences among the phases of the received signals received by a DSP (8) through the receivers (2-1 to 2-n) are the propagation delay differences of the received signals. Frequency data including frequency components is supplied to the receivers (2-n), which select the frequency data inside them and generate local oscillation signals of intermediate frequencies different from one another by orthogonal demodulation.

摘要： Systems and methods are directed to phase modulation of polar coordinates in a transmitter of wireless signals, to achieve high transmit power levels while meeting spectral mask and EVM requirements. An input signal is mapped to a sequence of modulation frequency (e.g., O-QPSK to MSK) to generate a mapped signal. A digital frequency shaping filter is applied to the mapped signal to generate a shaped signal. An adaptive rounding algorithm is applied to the shaped signal to generate a reduced bit-width signal. A digital frequency synthesizer is applied to the reduced bit-width signal to generate an analog waveform for transmission.
