11Pseudorandom noise — In cryptography, pseudorandom noise (PRN[1][2]) is a signal similar to noise which satisfies one or more of the standard tests for statistical randomness. Although it seems to lack any definite pattern, pseudorandom noise consists of a… …
12Multi-carrier code division multiple access — (MC CDMA) is a multiple access scheme used in OFDM based telecommunication systems, allowing the system to support multiple users at the same time. MC CDMA spreads each user symbol in the frequency domain. That is, each user symbol is carried… …
13IS-95 — Samsung cdmaOne mobile phone disassembled Interim Standard 95 (IS 95) is the first CDMA based digital cellular standard by Qualcomm. The brand name for IS 95 is cdmaOne. IS 95 is also known as TIA EIA 95. It is a 2G mobile telecommunications… …
14Near-far problem — The near far problem or hearability problem is a situation that is common in wireless communication systems, in particular, CDMA. In some signal jamming techniques, the near far problem is exploited to disrupt communications. Contents 1 Technical …
15Chip (CDMA) — In digital communications, a chip is a pulse of a direct sequence spread spectrum (DSSS) code, such as a pseudo noise code sequence used in direct sequence code division multiple access (CDMA) channel access techniques. In a binary direct… …
16Chaotic digital CDMA — was invented by Tao Yang and Leon O. Chua of the University of California, Berkeley in 1997. This is a chaotic spread spectrum CDMA communication technology where the message signal is first scrambled by an RF chaotic carrier and then sent to the …
