Abstract:
A method of providing a forward error correction for data services on a wireless system using code-division multiple-access (CDMA), the method comprising the step of:encoding data, in a wireless system employing CDMA, with a parallel concatenated convolutional code, the parallel concatenated convolutional code being a Turbo code comprising a plurality of constituent codes, wherein a plurality of data block sizes is used in conjunction with said Turbo Code and at least one of the plurality of constituent codes as a transfer function of: G(D)=[1, (1+D+D3)/(1+D2 +D3), (1+D+D2+D3)/(1+D2+D3)], wherein denotes unit delay in presentation of data bits.
