In the following paper we propose a new approach for extracting soft values from Mth order pulse position modulation (M-PPM). A new low-complexity algorithm is developed, where soft information for each data bit is calculated based on the power recei

In the following paper we analyze the performance of turbo codes, specified in IEEE 802.16 standard for broadband wireless access decoded by sub-optimal Chase Pyndiah algorithm. We have found out that the extended Hamming codes are 2.5 to 3dB from Sh
