Abstract

Abstract:

Layered space-time coding is a kind of space-time coding applied to multiple-input multiple-output system，which has a simple structure，easy to realize，and it’s bandwidth utilization shows a linear increase as antenna numbers increased，etc.In order to obtain more diversity gain and overcome system resistance decline，the paper presents a layered space-time hybrid coding architecture which is combined V-BLAST with space-time block coding（STBC）.At the same time，the latest progress of detection algorithm for layered space-time codes is presented.And it is introduced that the layered space-time codes is applied in free space optical communication and OFDM system.

Key words: BLAST, STBC, MIMO, decode
