incremental-phase modulation
1дифференциальная фазовая модуляция — Метод модуляции, используемый в системах с шумоподобными сигналами, при которой одна кодовая последовательность сдвигается во времени по отношению к другой, с целью улучшения условий выделения синхросигнала. [Л.М. Невдяев. Телекоммуникационные… …
2Numerically controlled oscillator — A numerically controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e. clocked), discrete time, discrete valued representation of a waveform, usually sinusoidal.[1] NCOs are often used in conjunction with a… …
3AZUSA — refers to a ground based radar tracking system installed at Cape Canaveral, Florida and the NASA Kennedy Space Center. AZUSA dated back to the early 1950s and was named after the southern California town (Azusa, California) where the system was… …
4Modem — For other uses, see Modem (disambiguation). A modem (modulator demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The… …
5High-Speed Downlink Packet Access — (HSDPA) is an enhanced 3G (third generation) mobile telephony communications protocol in the High Speed Packet Access (HSPA) family, also dubbed 3.5G, 3G+ or turbo 3G, which allows networks based on Universal Mobile Telecommunications System… …
6Enhanced Data Rates for GSM Evolution — Enhanced Data rates for Global Evolution (EDGE), Enhanced GPRS (EGPRS), or IMT Single Carrier (IMT SC) is a backwards compatible digital mobile phone technology that allows improved data transmission rates, as an extension on top of standard GSM …
7Edwin Howard Armstrong — Edwin H. Armstrong Developed and advanced the utility of FM technology. Born December 18, 1890(1890 12 18) New York, New York U.S …
8Singular value decomposition — Visualization of the SVD of a 2 dimensional, real shearing matrix M. First, we see the unit disc in blue together with the two canonical unit vectors. We then see the action of M, which distorts the disk to an ellipse. The SVD decomposes M into… …
9Peak programme meter — A typical British quasi PPM. Each division between 1 and 7 is exactly four decibels and 6 is the intended maximum level. A peak programme meter (PPM) is an instrument used in professional audio for indicating the level of an audio signal. There… …
10Chinese space program — This article is about the Chinese space program in general. For the current Chinese space agency since 1993, see China National Space Administration. The launch of Tianlian, Xichang Center The space program of the People s Republic of China is… …
