AB  - The introduction of 5G with excessively high speeds and ever-advancing cellular 
      device capabilities has increased the demand for high data rate wireless 
      multimedia communication. Data compression, transmission robustness and error 
      resilience are introduced to meet the increased demands of high data rates of 
      today. An innovative approach is to come up with a unique setup of source bit 
      codes (SBCs) that ensure the convergence and joint source-channel coding (JSCC) 
      correspondingly results in lower bit error ratio (BER). The soft-bit assisted 
      source and channel codes are optimized jointly for optimum convergence. Source 
      bit codes assisted by iterative detection are used with a rate-1 precoder for 
      performance evaluation of the above mentioned scheme of transmitting 
      sata-partitioned (DP) H.264/AVC frames from source through a narrowband 
      correlated Rayleigh fading channel. A novel approach of using sphere packing (SP) 
      modulation aided differential space time spreading (DSTS) in combination with SBC 
      is designed for the video transmission to cope with channel fading. Furthermore, 
      the effects of SBC with different hamming distances d(H,min) but similar coding 
      rates is explored on objective video quality such as peak signal to noise ratio 
      (PSNR) and also the overall bit error ratio (BER). EXtrinsic Information Transfer 
      Charts (EXIT) are used for analysis of the convergence behavior of SBC and its 
      iterative scheme. Specifically, the experiments exhibit that the proposed scheme 
      of error protection of SBC d(H,min) = 6 outperforms the SBCs having same code 
      rate, but with d(H,min) = 3 by 3 dB with PSNR degradation of 1 dB. Furthermore, 
      simulation results show that a gain of 27 dB Eb/N0 is achieved with SBC having 
      code rate 1/3 compared to the benchmark Rate-1 SBC codes.
