TSS902E

Viterbi and Reed–Solomon FEC Decoder

1. Description

Digital communication channels are inherently noisy,

making transmission error control essential for reliable

communication at low transmit power.

decoder (k=7) and

controller.

The convolutional deinterleaver, l=12 bytes for RS

(204, 188, T=8) configuration.

The outer decoder performs the second level error

protection, using a Reed Solomon (255, 239) error

correcting process.

The descrambler for energy dispersal removal.

A micro–processor interface to setup the device and

monitor the testability functions.

synchronization/clock

The TEMIC TSS902E is a single–chip Forward Error

Correction decoder; it conforms to the MPEG–II

transport layer protocol specified by ISO/IEC standard

and FEC requirements of Digital Video Broadcasting

(DVB) specification; its typical applications are DVB

satellites, regenerative multi–media transmission

satellites and military communications.

While monitoring the inner Viterbi decoder BER output,

the phase and the depuncturing pattern are tuned until

the Viterbi decoder proper alignment is found.

The TEMIC TSS902E capabilities rely on Viterbi and

Reed–Solomon decoding algorithms to achieve

extremely low bit–error rate (BER) on the transmitted

data. Allowing discontinuous data blocks transmission,

the TSS902E burst mode feature is unique.

The Viterbi decoder output feeds the deinterleaver and

Reed–Solomon decoder synchronization module. Once

the synchronization words have been found, the

deinterleaver, the outer Reed–Solomon decoder and the

descrambler are properly aligned.

The component is made of the following blocks:

The inner decoder which performs the first level

error detection and correction.

Each functional block may be by–passed, giving more

flexibility to a system designer.

This unit is made of a depuncturing block, a Viterbi
