PIPELINED CELL SITE BASE STATION RECEIVER FOR A SPREAD SPECTRUM SIGNALS |
摘要 |
An integrated modem (110) for use in a spread spectrum communications system. The modem includes in a demodulator front end (122) which despreads received multipath signals. A single transform engine (120), which operates on a time slice basis demodulates each despread multipath signal. The output of the transform processor engine (120) is provided to maximum detection circuitry (160) and a pipeline processor (126). Pipeline processor (126), which also operates on a time slice basis, combines and further processes the demodulated multipath signals to provide soft decision data for deinterleaving and error correction decoding in deinterleaver/decoder (130) to recover received data. The modem (110) further includes an encoder/interleaver (138), modulator (140) and transmit summer (142) for spread spectrum modulating data for transmission.
