| 摘要 |
Enhanced performance and increased capacity bandwidth efficient communications, broadcasting and telemetry systems are described. Spectral efficient transmitters-receivers (transceivers), high performance Bit Rate Agile (BRA) modulation-demodulation (Modem) methods and integrated Modems/Transceivers suitable for operation over Non-Linearly Amplified (NLA) (6.17) power efficient RF systems Cross-Correlated cascaded Time Constrained Signal (TCS) response processors (6.5) and Long Response (LR) filtered Bit Rate Agile (BRA) in phase (I) and quadrature phase (Q) baseband signals are disclosed. These spectral efficient high performance processing, transmitting and receiving methods are designated as Feher's Quadrature Phase Shift Keying (FQPSK) Transceivers. Bit rate and RF agile cascaded mis-matched (ACM) demodulation filters Miss-Matched (MM) to that of the modulator filters, Modem Format Selectable (MFS) and Code Selectable (CS) methods for tunable RF frequency embodiments are described.
