In this paper, we have first presented the construction of the linear characters of a finite Coxeter group G(n) of type B-n by lifting all linear characters of the quotient group G(n)/[G(n),G(n)] of the commutator subgroup [G(n),G(n)]. Also we show that the sets of distinguished coset representatives D-A and D-A' for any two signed compositions A, A' of n which are G(n)-conjugate to each other and for each conjugate class C lambda of G(n), where lambda is an element of BP(n), the equality |C lambda superset of D-A| = |C lambda superset of D-A'| holds. Finally, we have given the general structure of units of Mantaci-Reutenauer algebra.
