Abstract
A joint user detection apparatus for a wireless communication system, such as OFDM systems, arranged to account for timing impairments experienced by CAZAC codes. The proposed apparatus brings improvements over conventional receiving apparatuses by allowing joint user channel estimation processing and joint user equalization processing while considering timing impairments of user associated information present within a symbol of a received signal. The proposed solution could be used on conventional receiving apparatuses since both joint user channel estimation processing and joint user equalization processing can be activated independently such that either one or both improvements may be activated as needed or as required by the design of the conventional receiving apparatuses. A method and a computer program are also claimed.
