—The reverse link encoding steps of the IS95 cellular code-division multiple-access (CDMA) standard consist of con-volutional encoding, block interleaving, and orthogonal Walsh function encoding. Deinterleaving individual symbol metrics obtained from the Walsh function matched filters followed by conventional Viterbi decoding produces suboptimal results, as(More)
A linear method using optical ow to recover the translation direction of a moving camera has been previously presented. This algorithm produced a biased estimate and various compensation techniques have been proposed. The results of an error analysis of the diierent approaches containing expressions for the expected mean vectors and covariance matrices of(More)
