Описание
The present document (Direct Sequence - Code Division Multiple Access Methods, DS-CDMA) is to be used in
conjunction with part 1, describing the basic parameters common to all access methods. The present document specifies
the minimum requirements for system parameters of Direct Sequence - Code Division Multiple Access (CDMA)
Point-to-Multipoint (P-MP) Radio Systems in the terrestrial fixed services operating in the band 24,5 GHz to 29,5 GHz.
Only sections specific to CDMA are described in respect to the paragraphs stated in EN 301 213-1 [1].
Point-to-Multipoint Radio Relay Systems (P-MP) may use different access methods. As some technical parameters are
different for the various access methods, the standard is divided in five parts. A basic description of the different access
methods and a comparison among them is provided in TR 101 274 [5].
