Tham khảo tài liệu 'vehicular technologies increasing connectivity part 13', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Outage Performance and Symbol Error Rate Analysis of L-Branch Maximal-Ratio Combiner for K- and T - Fading 351 where J F1 - is Kummer confluent hypergeometric function defined in Wolfram http functions.wolfram.com 07.20.02.0001.01 . Lower bound for ASEP can be obtained by introducing 28 in 43 and using the same solution as in the previous case a T Lu-0.5 asePlb ---- Lu 0.5-Lu ụ 1 k I I b 1 K- I J_ _ _Ù f2nb r Lụ- exp K Y J 2 Y I 2Lk 1 K- Lụ- 0.5 Lụ - v------ỉ Y ụ 1 a Lụ- 1.5- 1 k ỹ b f 1 K-V 5 Lụ I 2 Y 48 2nb3 r Lụ IexP K YJ I I u3Lk K- 1 Lụ-1.5 Lụ- v 1 K Symbol Error Probability without diversity and for L-Branch MRC Fig. 11.

Average symbol error probability for coherent BPSK L 1 2 3 and 4 4.2 Symbol error probability analysis for maximal-ratio combiner in presence of n-p distributed fading To obtain ASEP at MRC output for r -g fading for non-coherent detection we introduce 34 in 38 ASEP a J exp -b y - frY dY 0 a_ -n 0 S V f -0.5 r c HL -0.5 yy 0 5 0 exp f 2uh i -I b - b Y I Y J h- -0.5 2 H- Y i - dY . Y J Integration of previous expression will be carried out via Meijer-G functions defined in Wolfram http functions.wolfram.com HypergeometricFunctions MeijerG . First we have to transform exponential and Bessel functions in Meijer-G functions in accordance to Wolfram http functions.wolfram.com 07.34.03.0228.01 and Wolfram http functions.wolfram.com 03.02.26.0009.01 . Integration is performed with Wolfram http functions.wolfram.com 07.34.21.0011.01 . After some algebraic manipulations and simplifications in accordance to Wolfram http functions.wolfram.com 07.34.03.0734.01 Outage Performance and Symbol Error Rate Analysis of L-Branch Maximal-Ratio Combiner for K- and T - Fading 353 and Wolfram http functions.wolfram.com 07.23.03.0079.01 we obtain closed-form expression for average SEP for non-coherent detection Lạ .
