Turbo detection of sphere packing modulation aided space-time coding schemes
Turbo detection of sphere packing modulation aided space-time coding schemes
In Chapters 2 and 3 of this thesis sphere packing modulated space-time signals designed for transmission over mobile wireless channels are proposed and investigated. Specifically, a recently proposed space-time signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design.
In Chapter 4, we propose a novel differential STBC (DSTBC) scheme that combines orthogonal design with sphere packing, referred to here as (DSTBC-SP), which provides performance advantages over conventionally modulated DSTBC schemes. Several bit-based and symbol-based schemes are proposed and investigated, demonstrating the performance advantages of DSTBC-SP systems. The proposed turbo-detected RSC-coded DSTBC-SP scheme exhibits a ‘turbo-cliff’ at Eb/N0 = 6dB and provides Eb/N0 gains of 23.8dB and 3.2dB at a BER of 10-5 over an equivalent-throughput uncoded DSTBC-SP scheme and a turbo-detected QPSK modulated DSTBC scheme, respectively.
In Chapter 5 we propose a three-stage turbo-detected STBC-SP scheme, where a rate-1 recursive inner precoder is employed to avoid the presence of a BER floor. Novel 3D EXIT chart analysis and its simplified 2D projections are employed for analysing and designing the proposed three-stage system with the aid of semi-analytic synthesis.

Abstract
In Chapters 2 and 3 of this thesis sphere packing modulated space-time signals designed for transmission over mobile wireless channels are proposed and investigated. Specifically, a recently proposed space-time signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design.
In Chapter 4, we propose a novel differential STBC (DSTBC) scheme that combines orthogonal design with sphere packing, referred to here as (DSTBC-SP), which provides performance advantages over conventionally modulated DSTBC schemes. Several bit-based and symbol-based schemes are proposed and investigated, demonstrating the performance advantages of DSTBC-SP systems. The proposed turbo-detected RSC-coded DSTBC-SP scheme exhibits a ‘turbo-cliff’ at Eb/N0 = 6dB and provides Eb/N0 gains of 23.8dB and 3.2dB at a BER of 10-5 over an equivalent-throughput uncoded DSTBC-SP scheme and a turbo-detected QPSK modulated DSTBC scheme, respectively.
In Chapter 5 we propose a three-stage turbo-detected STBC-SP scheme, where a rate-1 recursive inner precoder is employed to avoid the presence of a BER floor. Novel 3D EXIT chart analysis and its simplified 2D projections are employed for analysing and designing the proposed three-stage system with the aid of semi-analytic synthesis.
