Pulse-code modulation (PCM) is a method used to digitally represent analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital …

PCM/FM has been the primary modulation scheme used for such links for over 30 years, mainly due to its simplicity and reliability. Due to the longevity of PCM/FM, most airborne telemetry …

telemetry are Frequency Modulation (FM) and Phase Modulation (PM). Pulse Code Modulation (PCM)/Frequency Modulation (FM) has been the most popular telemetry modulation since …

illustrates a conceptual diagram of a PCM/FM communication system in which the source data is filtered, modulated, corrupted by Additive White Gaussian Noise (AWGN), and processed by …

discusses three of the main methods for the transmission of digital data: PCM/FM, PCM/PM and PSK. Most PCM telemetry data transmitted on the National Ranges currently use PCM/FM, …

CPM waveforms such as shaped-offset quadrature phase shift keying (SOQPSK) and pulse code modu-lation/frequency modulation (PCM/FM), which are currently used in military satellite and …

Similar detection efficiency to PCM/FM. Constant envelope waveform is ideal for efficient non-linear PA’s. Enhanced performance gained by increasing demodulator complexity. As the shop …

We present an approximation by which PCM/FM can be reinterpreted as a phase modulation scheme, allowing the use of coherent detection techniques. This is backward compatible with …

Computer simulations using the Constant Modulus Algorithm (CMA) have recently been reported for PCM/FM, ARTM Tier 1 SOQPSK, and Tier II SOQPSK. These encouraging results have …

The experimental results show that the use of FPGA chip to achieve digital signal processing algorithm for PCM-FM full digital baseband modulation can meet the requirements of a wide …
