Multiple access coding using bent sequences for mobile radio communications

Is made of orthogonal or two phase of the orthogonal symbol's digital message spread spectrum assigns a single harassment cover; and harass provided with a designation and harassment cover from the group. Selecting the set of harass guard to enable with any two code to harass guard the mould 2 is the constant amplitude, it does not rely on the cover body is a symbol and compares. In one embodiment, any two cover is mould 2 algorithm adding together, comprising Walsh conversion generating a layer of flat Walshe to chamber. A by a CDMA demodulation technology's wireless cellular telephone system, a digital key of the double-layer cryptographic system using pseudo-random generating inserted on the base harassment to cover and a ensuring consistency between datum the middle system level a specific cellular mobiles with the safety system. Similar, individual mobile user layer privacy be operation uses the key encryption personal information signal of the pseudo-random designed to ensuring consistency between datum of added.
