ABSTRACT:
Wireless digital communication systems apply an antenna diversity scheme to combat fading in a received signal as received by a receiver in the system. A radio apparatus having a single receiver front-end comprises a simple and robust antenna diversity scheme. In the system, digital radio signals are transmitted to the radio apparatus, wherein the transmitted radio signals comprise redundant information for allowing error correction at reception side. The error correction capability at reception side is applied for antenna diversity switching. Within the error correction capability of an error correction decoder comprised in the radio apparatus, the radio apparatus searches for a better antenna or antenna combination. When a better antenna or antenna combination is found, the receiver front-end is coupled to the better antenna or antenna combination.
