Chip spreading codes are bits in length
Web7.1.2 Short Code. Short codes are bit sequences with very specific autocorrelation functions. IS-95 uses a 2 15 - 1 = 32767 chip short code. For a first example let us use … Webwith a code called Short Code and then with one called Long code. Properties of spreading codes Multiplication with the code sequence which is of a higher bit rate, results in a much wider spectrum. The ratio of the code rate to the information bit rate is called both the spreading factor and the processing gain of the CDMA system. In IS-95 ...

Webdata rate of 1MBPS and a chip rate (rate of PN code) of 1MCPS will have a PG of 10.41dB. Using the PRISM chip set each data bit is x-ored with an 11 bit sequence for this particular example. The processing gain can be then viewed as the 10Log[11]dB where 11 is the length of the PN code. If a code with a length of 16 bits is to be used then the WebThe spread function for CCK is chosen from a set of M nearly orthogonal vectors by the data word. CCK uses one vector from a set of 64 complex (QPSK) vectors for the symbol and thereby modulates 6 bits (one of 64) on each 8 chips spreading code symbol. Two more bits are sent by QPSK modulating the whole code symbol.
WebGeneration of a scrambling codes • Spreading code is output of the binary shift register generator. • Pseudo random codes are used: cyclic. • Maximal length codes m-sequences: sequences that have maximal possible sequence given the length of the shift registers. • UL long scrambling code: complex scrambling codes, sum of two m-
