Abstract
In a method of complexity reduced noise floor estimation in a wireless communications system, determining, for a respective of at least a subset of a plurality of power grid points /c, a product of complementary cumulative distribution functions, each such function corresponding to a respective of a plurality j of provided wideband power measure estimates Ln a sliding window, and determining, for each of said at least subset of power grid points, a probability distribution function of a minimum of said plurality of wideband power measure estimates based on said determined product.

A computer-implemented method of complexity reduced noise floor estimation in a wireless communications system, said computer-implemented method comprising:
- determining, in a processor of a wireless communication device, for a respective one of at least a subset of a plurality of power grid points k, a product of complementary cumulative distribution functions, each said complementary cumulative distribution function corresponding to a respective one of a plurality j of provided wideband power measure estimates in a sliding window;
- and
- determining, in the processor of the wireless communication device, for each of said at least subset of power grid points, a probability distribution function of a minimum of said plurality of wideband power measure estimates based on said determined product.
A system for complexity reduced noise floor estimation in a wireless communications system, said system comprising:
- means for determining, for a respective one of at least a subset of a plurality of power grid points k, a product of complementary cumulative distribution functions, each corresponding to a respective one of a plurality of wideband power estimates i,
- means for determining, for each of said at least a subset of the plurality of power grid points, a probability distribution function of a minimum of said plurality of wideband power estimates i, based on said determined product.
A node in a wireless communications system, said node comprising:
- means for determining, for a respective one of a plurality of power grid points k, a product of complementary cumulative distribution functions, each said complementary cumulative distribution function corresponding to a respective one of a plurality of wideband power estimates;
- means for determining, for each of said plurality of power grid points, a probability distribution function of a minimum of said plurality of provided wideband power estimate distributions, based on said determined product.
