A Robust Cooperative Spectrum Sensing-Assisted Multiuser Resource Allocation Scheme

Algorithm 1

Robust cooperative spectrum sensing-assisted multiuser resource allocation scheme.

The Proposed Rope-Alone

Step  1. Each SU performs local robust spectrum sensing on each subcarrier,

then sends the sensing results and the channel state information to the SBS

through the uplink reporting link.

Step  2. The SBS performs subcarrier allocation according to (26) and set

appropriate initial values to the dual variables , and for , .

Step  3. calculate the value of from (29).

Step  4. Substitute and the dual variable into (B.6)/(B.7)/(B.8), update the dual variables.

Step 4. If the conditions of

,

,

and,

are satisfied simultaneously, then terminate the algorithm. Otherwise, jump to Step  3
