Taylor expansion is employed to linearize the nonlinear confluent hypergeometric function. Accordingly, a closed-form expression can be derived in the E-step and the complexity of the proposed algorithm can be significantly reduced.
where [[OMEGA].sub.d] = E([R.sup.2]) denotes the average power of desired information signal, while [F.sub.1](a,b,z) and [GAMMA](a) denote the confluent hypergeometric function [10, Eq.(9.210/1)] and Gamma function [10, Eq.
The inverse symbolic calculator is unable to give us the representation of 0.97210699*** using standard special functions, but we have tried to give its representation using error function representation as hypergeometric function ; we have

Here, [F.sub.1]([alpha], [beta], [beta]', [gamma]; x; y) is the Appel hypergeometric function with two variables.
where [psi](*) is the degenerate hypergeometric function (see, e.g., ), and C is a constant to be determined.
Equation (13) differs from the generalized hypergeometric function [sub.p][F.sub.q](z) defined in (9) only by a constant multiplier.
