ГЕНЕРАЦИЯ БИТОВЫХ ПОТОКОВ С ПОВЫШЕННОЙ ЭФФЕКТИВНОСТЬЮ СЖАТИЯ |
摘要 |
A system ( 10 ) and method that generate bit-streams that result in higher compression gains. The system is akin to a normal 1-bit SDM. Internally, the system ( 10 ) tries to find the best possible bit sequence by tracing N possible solutions at every time instant. In an implementation, the system has N>I trellis path structures ( 20 ). Every path is used to track a possible output bitstream. The quality of a bitstream is determined by measuring the (frequency weighted) difference between input and output; it is this measure that is reduced or minimized. |
