A method for transmitting and receiving data in a communication system includes adding symbols to both ends of a transmitted signal block, filtering the transmitted signal block, removing the symbols from the filtered transmitted signal block and transmitting the transmitted signal block to a receiver through a channel. A transmitter includes a controller configured to add symbols to both ends of a transmitted signal block through the symbol adder, filter the transmitted signal block, remove the symbols from the filtered transmitted signal block through the symbol remover, and transmit the transmitted signal block through the transceiver to a receiver through a channel. A receiver includes a controller configured to add symbols to both ends of the received signal block through the symbol adder, filter the received signal block and reconstruct data from the received signal block.
