Cooperative-MIMO Communications

Spatial subchannel codes for wireless devices operating in a cooperative antenna array are generated using an asymptotically optimal decoding algorithm, such as a trellis-exploration algorithm similar to the Viterbi algorithm. A trellis may be constructed using a number of desired subchannels, at least one code length, and a number of code-chip parameters. A fitness function is derived from a mathematical relationship between codes, and may include some measure of correlation of the codes. The selected codes correspond to paths having optimal path metrics derived from the fitness function. Multiple iterations through the trellis may be performed to refine a selection of the codes.

InactiveCN101888297ASolve complex processSimplify the cross-domain authentication processUser identity/authority verificationTrust relationshipAuthentication server
The invention relates to a trust-based cross-domain authentication method. The conventional method has the disadvantages of poor compatibility and low efficiency. The method comprises that: a first authentication server in a first trust domain performs identity authentication on a first entity, and sends an authentication result to a second authentication server in a second trust domain; the second authentication server verifies whether the first authentication server is lawful by utilizing the pre-established PKI authentication-based trust relationship, if the first authentication server is lawful, the process is continued, and if the first authentication server is not lawful, the process is finished; and finally, the second authentication server judges whether the received authentication result indicates the first authentication server passes the authentication, if the authentication result indicates the first authentication server passes the authentication, the cross-domain authentication is successful, and if the authentication result indicates the first authentication server does not pass the authentication, the cross-domain authentication is failed. The method simplifies the cross-domain authentication flow and improves the cross-domain authentication efficiency.
