In the three preliminary sections to the article we define two operations on finite sequences which seem to be of general interest. The first is the cut operation that extracts a contiguous chunk of a finite sequence from a position to a position. The second operation is a glueing catenation that given two finite sequences catenates them with removal of the first element of the second sequence....

In this paper, basis in SC-FDMA uplink systems is investiga greedy algorithms are proposed allocation at each transmission time interval. Selection criteria based on spectral efficiency and fairness are also proposed to choose the final allocatio transmission time interval. Simulation results show that when the number of users and the velocity of the users were varied, the improved algorithms t...
