Matlab Implementation of the Viterbi Decoder This program asks number of outputs to be generated for input of one bit(nc),length of code(l), the constrain length(kc), number of errors to be added to ...

Convolutional coding and Viterbi decoding, along with binary phase-shift keyed modulation, is presented as an efficient system for reliable communication on power limited satellite and space channels.

Abstract: Attenuation, interference, noise, and distortion affect any wireless communication system's data transfer, making it more difficult for the receiver to receive precise data. Convolution ...

Viterbi decoder is the dominant module to determining the power consumption of the system. High speed and low power design of Viterbi decoder with data rate1/2 and convolution encoding with a ...

Clearly, wireless LAN (WLAN) systems are a hot topic in the design community. With 802.11b taking off, and 802.11g and 802.11a coming quickly, much attention has been placed on building WLAN access ...
