Abstract
This invention relates to a symbol deinterleaver for digital video broadcasting system. By partitioning the entire deinterleaver memory into four individual blocks and properly allocating these blocks to store the data according to its odd/even and high/low index, the size of deinterleaver memory can be reduced by a half compared with the conventional techniques. In addition, since the possibility of memory access to the same memory block at the same clock cycle is minimized such that the deinterleaver can be implemented using single-port memory with small additional buffer with size only about 0.5% of the entire memory. Furthermore, the invention also proposes an address generator for the deinterleaving address computation. The proposed techniques of the invention can effectively reduce the circuit size of the symbol deinterleaver to help lowering the overall chip cost of digital video broadcasting receivers.
