Abstract: A method for bit interleaving is provided. A method includes mapping a set of bits a?{ak: k=0, 1, 2, . . . Npost?1} to an array B={Bi,j: i=0, 1, 2, . . . , M?1; j=0, 1, 2, . . . , N?1} such that bit ak maps to Bk mod M, ?k/M?, wherein mod denotes the modulo operator, ? ? denotes the floor operator, and M and N are constants, performing at least one of—a first permutation operation comprising permuting two or more bits within each of one or more first groups of bits, wherein each first group of bits is defined by G(1)p={Bi,p: i=0, 1, 2, . . . , M?1; p?{0, 1, 2, . . . , N?1}} and—a second permutation operation comprising permuting two or more bits within each of one or more second groups of bits, wherein each second group of bits is defined by G(2)q={Bq,j: j=0, 1, 2, . . . , N?1; q?{0, 1, 2, . . . , M?1}} and de-mapping bits from B to obtain an interleaved set of bits b?{bk: k=0, 1, 2, Npost?1} such that bit Bi,j is de-mapped to bit bNi+j.

Abstract: A method for estimating qualities of links between a transmitter and a receiver on respective carrier frequencies in a multi-carrier wireless communication system from measurements made during a scanning interval in which pilot signals may be transmitted from the transmitter to the receiver in a plurality of carrier-time bins, each carrier-time bin corresponding to a respective carrier frequency of the multi-carrier system and a respective time slot within the scanning interval, are provided.
