Frequency domain multi‐user receivers for IEEE 802.15.4a short‐range communication network

Abstract

ABSTRACTIn this letter, we propose frequency domain receivers for an IEEE 802.15.4a short‐range communication network: the uplink case is taken into account, considering a scenario where several devices communicate with a coordinator node. The channel model has been also derived according to the IEEE 802.15.4a recommendations. Results show that the proposed approach can be beneficial in short‐range systems under severe conditions of multipath propagation and interference. An interesting novelty of the proposed approach is that both single‐user and multi‐user FD receivers based on the minimum mean square error criterion can be derived by exploiting the zero padding technique which is intrinsic in the symbol structure of the standard.
