What is interleaving in GSM Technology
Answer:
★ Time diversity in a signal communication system is obtained by using Interleaving.
★ The possibility of losing whole bursts will be decreased by interleaving
★ Total 456 bits from convolution encoder, including 20ms of speech, is subdivided into eight blocks. Each block consists of 57 bits.
★ All these blocks are transmitted in consecutive time slots.
★ Enough information is available in 7 blocks, in case one of the blocks is lost due to burst errors. This enables whole segment recovery by using error correction.
