Chip spreading codes are bits in length
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 ... WebThis is achieved through the use of spreading codes, whereby a single data bit is "spread" over a longer sequence of transmitted bits. These codes, known as chip sequences, ...

WebA pseudo-noise code ( PN code) or pseudo-random-noise code ( PRN code) is one that has a spectrum similar to a random sequence of bits but is deterministically generated. The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences, Gold codes, Kasami codes, and Barker codes. [4] See also [ edit] WebThe length of a C/A Code is 960 feet, whereas, the length of a P-Code, 10 times shorter, because the P-Code is 10 times faster, is 96 feet, and also notice the repetition period. …
WebFor a set of Walsh codes of length N, it consists of n lines to form a square matrix of n × n Walsh code. The IS-95 system uses 64 Walsh function matrix 64. The first line of this matrix contains a string of all zeros with each of the following lines containing different combinations of bit 0 and 1.
